Mastering Mouse Keys: Keyboard-Driven Pointer Control in Windows

ChatGPT · Aug 12, 2025

Windows includes a built-in accessibility feature called Mouse Keys that lets you use the numeric keypad to move the pointer, click, double-click, and drag items—no mouse required—and the feature is available in both Windows 10 and Windows 11.

Background

Mouse Keys is an accessibility feature that has been part of Windows for many releases. It was designed to help users who have limited use of a traditional pointing device, but it also serves practical purposes for anyone whose mouse fails, for keyboard-first workflows, and for remote or headless scenarios where a physical mouse isn’t available. In recent Windows versions the feature is surfaced in Settings under Accessibility, while legacy Control Panel options remain available for users on older builds or for more granular configuration.
The feature maps the numeric keypad keys to pointer movement and mouse-button actions, and Windows exposes additional options—speed, acceleration, and hotkey toggles—to shape how Mouse Keys behaves in day-to-day use. These behaviors and mappings are stable across modern Windows releases; however, some laptop keyboards, compact layouts, and international keymaps can affect the exact key behavior.

How Mouse Keys works — the mechanics

Mouse Keys turns the numeric keypad into a virtual pointing device. The core vocabulary of the feature is straightforward:

The numeric keys 8, 2, 4, and 6 move the pointer up, down, left, and right respectively.
The diagonal moves are mapped to 7, 9, 1, and 3.
The 5 key performs the active mouse button click (left by default).
The forward slash (/), asterisk (*), and minus (-) select the left button, both buttons, or the right button as the “active” mouse button.
The 0 (zero) key locks the active button down for drag operations; the decimal point (.) releases the lock.
Additional settings let you change pointer speed and acceleration, and you can configure a modifier to temporarily speed up or slow down pointer movement (commonly Ctrl to speed up and Shift to slow down).

This design mirrors the basic mechanics of a physical mouse—movement, button selection, clicks, double-clicks, and drag/release—while remaining entirely keyboard-driven. Because the mapping is numeric-keypad-centric, Mouse Keys requires a numeric keypad or a keyboard that can emulate one (some laptops offer an integrated numpad via a function layer).

Where to find Mouse Keys and how to enable it

Windows 11 (recommended path)

Open Settings and select Accessibility.
Scroll to Interaction and choose Mouse.
Enable the Mouse keys toggle.

After enabling the toggle, the numeric keypad will control the pointer according to the standard mappings. Within the same settings page you can fine-tune behavior such as pointer speed, acceleration, and whether Num Lock is required for Mouse Keys to operate.

Windows 10 (Control Panel path)

Open Control Panel and go to Ease of Access → Ease of Access Center.
Choose Make the mouse easier to use.
Under Control the mouse with the keyboard, check Turn on Mouse Keys.
Click Set up Mouse Keys for pointer speed and other options.

Both Windows 10 and Windows 11 provide a keyboard shortcut to toggle Mouse Keys: pressing Left Alt + Left Shift + Num Lock will prompt you to enable or disable Mouse Keys. This is handy for quickly switching between a mouse and keypad control, but care must be taken to avoid accidental activation.

Step-by-step quick reference (consumer-ready)

Enable Mouse Keys through Settings (Windows 11) or Control Panel (Windows 10).
Ensure Num Lock behaves as required (some systems default Mouse Keys to work only when Num Lock is on).
Use numeric keypad:
8 = up, 2 = down, 4 = left, 6 = right
7, 9, 1, 3 = diagonals
5 = click (active button)
/ = select left button
= select both buttons
= select right button
= double-click (with left button active)
0 = press-and-hold (start drag)
. = release (drop)
Adjust pointer speed and acceleration settings in the same configuration area to match your comfort.
Use Left Alt + Left Shift + Num Lock to toggle on/off quickly (respond to the dialog box with Enter or Space to confirm).

Advanced options and tweakable settings

Windows exposes a handful of useful controls that make Mouse Keys practical beyond the default, slow, single-pixel moves:

Pointer speed: Top speed and acceleration sliders let you tune responsiveness so movement can go from pixel-precise to reasonably fast across the screen.
Modifier keys for temporary speed: Many builds include the option to Hold Ctrl to speed up and Shift to slow down while moving the pointer—useful for precision work and long-distance jumps in the same session.
Num Lock requirement: By default Mouse Keys may only work when Num Lock is on, but you can change that so Mouse Keys operates independently of Num Lock. This is especially useful on laptops without a dedicated numeric keypad or where Num Lock toggling interferes with normal typing.
Audible feedback: Windows can play a sound when Mouse Keys is switched on or off, which helps users confirm state changes without relying on a visual indicator.
Control Panel legacy options: The old Ease of Access / Set up Mouse Keys panel still exists and can offer a slightly different layout for pointer speed and toggles; it’s useful when troubleshooting or when working on older Windows builds.

Practical uses and benefits

Accessibility: Mouse Keys was built to support users who cannot use a mouse due to motor impairments. It remains a core assistive technology in Windows accessibility toolkits.
Broken or disconnected mouse fallback: If a mouse dies or is unavailable, Mouse Keys delivers an immediate way to continue working without interrupting workflow.
Remote and headless systems: When interacting with remote desktops or virtual machines where pointer devices are not present or poorly transmitted, the numeric keypad can offer a reliable local control method.
Keyboard-centric workflows: Power users who prefer staying on the keyboard can use Mouse Keys for precise pointer movement without reaching for a mouse.
Precise micro-movements: Because Mouse Keys supports step-based movement and fine speed adjustment, it can be useful for pixel-level positioning in graphics or layout work.

Limitations and potential risks

Requires a numeric keypad: Compact keyboards and many laptops lack a dedicated numeric keypad; on those devices Mouse Keys either requires a function-layer numeric pad (which can be confusing) or simply won’t be available.
Accidental activation: The Alt + Shift + Num Lock shortcut is easy to hit unintentionally. Accidentally turning Mouse Keys on can disrupt typing or numeric entry, leading to confusion. Configure the shortcut or disable it in settings if it’s a nuisance.
Typing vs pointer conflict: If Mouse Keys is active and Num Lock behavior isn’t configured as desired, numeric entry can be disrupted—users may type numbers and see the pointer move instead.
Performance and ergonomics: For fast pointer movement or gaming, Mouse Keys is not a substitute for a mouse. It offers accessibility and utility, not performance parity.
Modifier key complexity: Using Ctrl to speed up or Shift to slow down requires mental context switching and can be awkward for users who rely on sticky keys or other accessibility aids.
Compatibility with custom layouts and international keyboards: Keyboard layouts that map numeric keypad keys differently or laptops with alternative key naming may experience inconsistent behavior. Some third-party keyboards map keys nonstandardly and can break assumed mappings.
Security implication (minor): Because Mouse Keys can be activated by a simple keyboard sequence, a local attacker with keyboard access could toggle pointer control. This is a low-risk scenario but worth noting in sensitive environments.

Any claim about a specific laptop model’s behavior with Mouse Keys or a vendor’s custom driver should be confirmed per-device; behavior can vary, and those device-specific details are best verified against the manufacturer’s documentation.

Troubleshooting: common problems and fixes

Mouse Keys doesn’t move the pointer:
Confirm Mouse Keys is enabled in Settings or Control Panel.
Verify Num Lock status and whether the option “Only use Mouse Keys when Num Lock is on” is set.
Numeric keypad types numbers instead of moving the pointer:
Ensure Mouse Keys is turned on and that Num Lock is in the expected state for your configuration.
Left Alt + Left Shift + Num Lock shortcut doesn’t work:
The prompt may appear but fail if modifier keys are remapped or if the keyboard driver intercepts the combination. Try enabling Mouse Keys directly from Settings.
Movement is too slow or too fast:
Adjust Pointer speed and Acceleration sliders in the Mouse Keys settings, and enable the Ctrl/Shift speed modifiers if needed.
Drag-and-drop won’t work with 0 and .:
Make sure you first select the active button (usually with the / key for left click), then press 0 to latch, move with numeric keys, and press . to release.
Laptop Fn-layer numpad doesn’t respond:
Some laptops require pressing Fn + Num Lock to activate the embedded keypad. Consult the laptop’s documentation for the correct Fn behavior.

When encountering unexplained behavior, rebooting and testing with a different keyboard (or an external numpad) can isolate whether the issue is hardware- or OS-related.

Alternatives and complementary tools

On-Screen Keyboard: Windows ships an on-screen keyboard that includes a numeric keypad; combined with mouse or touch input, it can provide some of the same capabilities.
Third-party utilities: Tools such as AutoHotkey can remap keys to simulate pointer movement or create custom key combinations beyond the built-in Mouse Keys behavior.
Touch and touchpad gestures: Modern laptops’ precision touchpads and touchscreens often provide alternate pointer control that can replace the need for Mouse Keys in some scenarios.
Assistive devices: Trackballs, head-tracking cameras, and specialized switches can offer more ergonomic or performance-appropriate solutions than the numeric keypad in specific accessibility contexts.
Voice control and eye-tracking: For those unable to use manual input devices, voice command systems and eye-tracking can be paired with pointer-control utilities to create fully hands-free workflows.

Each alternative has trade-offs in cost, learning curve, and compatibility; for many users, Mouse Keys is a zero-cost, low-friction first step.

Best practices for everyday use

Customize pointer speed first: Before relying on Mouse Keys for extended tasks, spend a few minutes adjusting top speed and acceleration to avoid repeated frustration.
Decide Num Lock behavior: Choose whether Mouse Keys should require Num Lock. For full-time keyboard pointer control, disable the Num Lock requirement; for intermittent use, require Num Lock to avoid accidental activation.
Disable the hotkey if necessary: If you or others frequently trigger the toggle accidentally, disable the keyboard shortcut in accessibility settings to prevent unintended switches.
Train with small tasks: Practice clicking, double-clicking, and drag-and-drop on simple desktop icons before attempting precision tasks.
Pair with screen magnifier if needed: Users who need larger UI elements can combine Mouse Keys with zoom tools to improve accuracy.
Document your setup: If deploying Mouse Keys in an organizational or support context, document whether Num Lock is required and any custom modifier behavior so others can operate the system reliably.

Enterprise and deployment notes

For IT teams and administrators, Mouse Keys can be configured or disabled via group policy or deployment scripts depending on organizational needs. When rolling out accessibility features across a fleet, consider standardizing settings for Num Lock behavior and audio cues to reduce user confusion. Training materials and a short quick-start reference sheet will significantly reduce support tickets related to accidental activation and basic usage.
Additionally, because Mouse Keys is an OS-level accessibility feature, it is compatible with screen readers and other assistive technologies, but administrators should validate combined behavior in their specific environment to ensure no conflicts with custom input drivers or security software.

Final analysis — strengths, practical value, and caveats

Mouse Keys is a robust, decades-old accessibility feature that continues to serve a practical role in modern Windows environments. Its strengths are clear: it’s built into Windows, requires no additional software, adapts to both legacy Control Panel and modern Settings flows, and provides a full set of pointer operations (movement, click selection, double-click, drag/release). The configurable speed and modifier options make it flexible for both fine-grain control and faster navigation.
On the risk/limitation side, Mouse Keys is inherently dependent on the presence or emulation of a numeric keypad. Compact laptops, 60% keyboards, and non-standard external keypads can complicate uptake. Accidental activation by a keyboard shortcut is a frequent user complaint and can be easily managed by disabling the hotkey or adjusting settings. For scenarios requiring high pointer throughput—fast gaming, rapid UI navigation—Mouse Keys is not a replacement for a dedicated pointing device.
Because device manufacturers and custom drivers can alter baseline keyboard behavior, any device-specific claims (for example, exact Fn key interactions on a particular laptop model) should be validated against that vendor’s documentation. The built-in Windows guidance and multiple independent tech resources consistently document the core keystroke mappings and settings described here, making the procedural guidance reliable across supported Windows editions.

Mouse Keys remains one of those quietly indispensable Windows features: unobtrusive until needed, powerful in constrained situations, and flexible enough for both accessibility and everyday fallback scenarios. Properly configured and understood, it keeps workflows moving when a physical mouse cannot, and it gives users another dependable way to interact with the desktop using only the keyboard.

ChatGPT · Aug 12, 2025

Mouse Keys is one of Windows’ oldest and most practical accessibility tools: it lets you steer the mouse pointer using the numeric keypad, perform clicks, double‑clicks, and drag‑and‑drop — all from the keyboard. Microsoft’s original support documentation dates back to Windows 7 and spells out the numeric mappings and click controls, while modern Windows 10 and Windows 11 settings expose more granular speed, acceleration, and modifier options to tailor the experience to today’s keyboards and displays. (support.microsoft.com, windowscentral.com)

Background / Overview

Mouse Keys was created to help people who have difficulty using a conventional mouse by mapping pointer movement and button actions to the numeric keypad. Historically the feature has been documented in Microsoft’s Ease of Access (Control Panel) pages for older Windows releases; contemporary Windows releases move those settings into the Accessibility area of Settings and add sliders and modifier keys for improved responsiveness. The core mechanics — numeric keypad directions for movement, keys for selecting which mouse button is active, a key to “lock” a click for dragging, and a key to release — remain remarkably consistent across versions, though the exact activation dialogs and some multi‑key click sequences can vary between releases. (support.microsoft.com, howtogeek.com)
This article explains how Mouse Keys works across Windows versions, gives step‑by‑step instructions for enabling and customizing it, highlights practical usage scenarios, offers troubleshooting and safety considerations, and provides a short cheat‑sheet you can keep handy the next time you need to navigate without a mouse.

How Mouse Keys works (the essentials)

Movement

The numeric keypad controls pointer movement:
7 = up-left, 8 = up, 9 = up-right
4 = left, 6 = right
1 = down-left, 2 = down, 3 = down-right. (support.microsoft.com, windowscentral.com)

These keys nudge the pointer by small increments, and modern Windows versions let you scale that increment using speed and acceleration settings.

Selecting buttons and clicking

Select which mouse button is active:
/ (forward slash) = select left button
(asterisk) = select both buttons (often used for combined actions)
(minus) = select right button. (support.microsoft.com)
Once a button is selected:
Press 5 to perform the active click (left or right depending on selection).
Use 0 (zero) to lock the active button down for dragging.
Press . (decimal) to release the locked click (drop the item).
A double‑click gesture may be performed by a plus sign (+) or by a combined hold‑and‑press depending on Windows version and documentation; this is an example of where instructions diverge between sources, so treat the exact sequence as version‑dependent (see “Version quirks” below). (support.microsoft.com, windowscentral.com)

Activation and quick toggle

In older Windows: Mouse Keys settings live in Control Panel → Ease of Access → Make the mouse easier to use. (support.microsoft.com)
In Windows 10 and Windows 11: Settings → Accessibility (or Ease of Access in older Windows 10 builds) → Mouse → toggle “Mouse keys”. You can also reach these pages with a quick Settings search for “mouse keys.” (howtogeek.com, windowscentral.com)
There is a universal keyboard shortcut to prompt enabling/disabling Mouse Keys: Left Alt + Left Shift + Num Lock. Press the shortcut and confirm the dialog to toggle Mouse Keys on/off. This shortcut is supported widely across Windows versions. (computerhope.com)

Step‑by‑step: enabling Mouse Keys (Windows 11 and Windows 10)

Follow these concise, tested steps — use the section appropriate for your Windows release.

Windows 11 (Settings)

Press Windows + I to open Settings.
Click Accessibility, then scroll to Interaction → Mouse.
Flip the Mouse keys switch to On.
Optionally:
Uncheck Only use mouse keys when Num lock is on if you prefer to use Mouse Keys regardless of Num Lock.
Use the Mouse Keys Speed and Mouse Keys Acceleration sliders to tune responsiveness.
Enable Hold the Ctrl key to speed up and the Shift key to slow down for momentary pointer speed changes. (howtogeek.com, windowscentral.com)

Windows 10 (Control Panel / Settings)

Open Settings → Ease of Access → Mouse (or Control Panel → Ease of Access Center → Make the mouse easier to use).
Toggle Control your mouse with a keypad (or Turn on Mouse Keys).
Click Set up Mouse Keys (Control Panel path) to adjust pointer speed, acceleration, sound feedback, and whether mouse keys require Num Lock. (windowscentral.com, tenforums.com)

Universal keyboard activation

Press Left Alt + Left Shift + Num Lock to immediately display a confirmation dialog to turn Mouse Keys on or off. Confirm with Space or Enter. (computerhope.com)

Quick reference: numeric keypad cheat‑sheet

Movement: 7 8 9 / 4 6 / 1 2 3 (diagonals + cardinals). (support.microsoft.com)
Click/select: 5 = perform active click (needs / or - to choose left/right first). (support.microsoft.com)
Select left button: / (forward slash). (support.microsoft.com)
Select both buttons: * (asterisk). (support.microsoft.com)
Select right button: - (minus). (support.microsoft.com)
Drag lock: 0 (zero) to press and hold active button; . (decimal) to release. (support.microsoft.com)
Double‑click: + (plus) in some docs, or hold * then press + in others — see Version quirks. (support.microsoft.com, windowscentral.com)

Keep this cheat‑sheet printed or memorized — once you get used to the layout, Mouse Keys can perform nearly any pointer operation.

Version quirks, inconsistencies, and what to watch for

Microsoft’s official support article originally addresses Windows 7 and documents the core mapping and click behavior clearly (including a simple plus sign (+) for double‑click). That page remains a canonical record of the original mechanics. (support.microsoft.com)
Modern guides for Windows 10/11 (third‑party how‑to sites and Microsoft’s updated UX documentation) add new toggles, speed/acceleration sliders, and modifier keys (Ctrl/Shift) to temporarily change pointer speed. They may also document slightly different sequences for compound actions like double‑clicking (some modern guides recommend holding * then pressing + to reliably double‑click). This reflects minor evolution and slight differences in wording rather than a wholesale change to the feature. Always follow the version‑specific Settings dialog on your PC if in doubt. (howtogeek.com, windowscentral.com)
Laptop keyboards without a dedicated numeric keypad: many laptops use an integrated number pad via Fn + NumLock or use number mappings on letter keys (U, I, O, J, K, L, etc.). When that overlay is active, Mouse Keys will usually follow the same mappings — but the route to enable Num Lock or to use Fn may differ by vendor. Consult your laptop manual for vendor‑specific Fn + NumLock behavior. (computerhope.com)
If a documentation source conflicts with another (for example, double‑click instructions), treat the official Settings dialog on your Windows machine as authoritative; the UI and tooltips there reflect the OS version you’re running. When in doubt, test the sequence with a small, safe target (like a folder or text file) before relying on it in a critical task. (support.microsoft.com, windowscentral.com)

Practical use cases and benefits

Accessibility: For users with limited hand mobility or tremors, Mouse Keys offers a reliable alternative to fine motor control required by a physical mouse. It enables precise pointer placement and complex operations like drag‑and‑drop without requiring simultaneous pressure on a mechanical mouse. (support.microsoft.com)
Emergency scenarios: When a mouse is lost, broken, or temporarily unavailable (dead batteries, unresponsive driver), Mouse Keys lets you continue working rather than rebooting to troubleshoot. (computerhope.com)
Precision work: For pixel‑level placement the keypad can be steadier than a jittery physical hand movement, useful in detailed graphic or layout work when combined with pointer speed adjustments. (windowscentral.com)
Keyboard‑only workflows: For power users who prefer keyboard navigation, Mouse Keys makes it possible to remain in a keyboard-centric workflow even for pointer‑oriented tasks such as selecting contextual UI elements and dragging items. (howtogeek.com)

Troubleshooting and tips

If Mouse Keys “doesn’t work,” first confirm Num Lock behavior: most configurations require Num Lock to be active unless you explicitly disabled the “Only use mouse keys when Num Lock is on” option in Settings. Toggle Num Lock and listen for the confirmation beep found in some systems. (howtogeek.com, computerhope.com)
Use the Speed and Acceleration sliders: at default settings movement can feel painfully slow. Raising the top speed and acceleration in Settings or Control Panel transforms Mouse Keys into a practical, fast input method. (howtogeek.com)
Use modifier keys for on‑the‑fly speed control: enabling “Hold the Ctrl key to speed up and the Shift key to slow down” gives you a fast, momentary speed change when moving the pointer across large distances. (howtogeek.com)
Laptops and small keyboards: if your laptop uses a function overlay for numeric keys, you may need to press Fn + NumLock or even change a BIOS/firmware setting to prioritize Num Lock. If in doubt, check the vendor’s support pages for model‑specific instructions. (computerhope.com)
If double‑click doesn’t behave as expected, try both sequences: (a) ensure left button is active then press + once, and (b) hold * and press +. Behavior can vary by Windows build and by whether your machine is using legacy Control Panel settings or modern Accessibility settings. (support.microsoft.com, windowscentral.com)

Security, privacy and reliability considerations

Mouse Keys is a purely local accessibility feature: it does not transmit data off device, does not require internet connectivity, and does not incur privacy risks beyond normal OS usage. It is a low‑risk tool from a security perspective. (support.microsoft.com)
Reliability: because Mouse Keys uses core OS input handling, it’s generally reliable across system states. However, driver problems, locked input focus, or applications that capture raw input (e.g., fullscreen games or specialized CAD tools) may interfere with expected behavior. In these cases, exit the interfering app or switch focus to the desktop while using Mouse Keys. (computerhope.com)
Accessibility consistency: if you rely on Mouse Keys in professional or assistive contexts, verify your specific Windows build and configuration before using it for critical tasks — UI wording and default toggles changed between Windows 7, early Windows 10 builds, and Windows 11. Always test workflows after system upgrades. (support.microsoft.com, windowscentral.com)

Advanced tweaks and automation

Registry toggle: advanced users and IT administrators can toggle Mouse Keys per user with a registry value under HKEY_CURRENT_USER\Control Panel\Accessibility\MouseKeys (Flags value). This is useful for scripted provisioning of accessibility settings for specialized deployments, but modifying the registry carries normal system risks and requires administrative care. (tenforums.com)
Taskbar icon and quick access: Windows can show a Mouse Keys icon in the notification area when active; for quick toggling pair that with the keyboard shortcut (Alt + Left Shift + NumLock) for minimal fuss. (tenforums.com)
Pairing with on‑screen keyboard: on touch devices or devices without a numeric keypad, the On‑Screen Keyboard (OSK) can expose a numeric keypad for Mouse Keys control — although the experience is slower and less practical than a physical numeric keypad. (computerhope.com)

Strengths and limitations — critical analysis

Strengths

Simplicity and ubiquity: Mouse Keys has been present across many Windows versions and requires no additional installs, making it a dependable fallback tool. (support.microsoft.com)
Granular control: Modern sliders and modifiers (Ctrl/Shift) introduced in Windows 10/11 improve speed control and make Mouse Keys useful for both precision and long‑distance pointer movement. (howtogeek.com)
Low‑risk: Because it’s built into the OS and adds no network exposure, it’s safe for assistive use in sensitive environments. (support.microsoft.com)

Limitations and risks

Ergonomics: extended use of the numeric keypad for pointer control is not necessarily ergonomic; long sessions may strain the hand or wrist in people not adapted to keypad use.
Keyboard dependence and hardware variability: many modern laptops lack a dedicated numeric keypad, so Mouse Keys is less accessible on those devices without an external keypad or OSK. Vendor‑specific Fn mappings can further complicate use. (computerhope.com)
Version and documentation differences: as noted, some documentation differs on compound actions (double‑click sequences or combined hold actions). This can confuse users migrating between Windows versions; always test on your exact build. (support.microsoft.com, windowscentral.com)
App compatibility: applications that capture raw HID input or run in exclusive full‑screen modes can block Mouse Keys. In those cases fallback options include switching to windowed mode or using alternative accessibility tools (e.g., on‑screen pointer utilities or voice control). (computerhope.com)

When to choose Mouse Keys vs alternatives

Choose Mouse Keys when:
You need precise, keyboard‑driven pointer control without installing third‑party software.
You’re on a desktop with a dedicated numeric keypad or have a reliable laptop Fn/NumLock mapping.
You require a built‑in, secure accessibility feature for sensitive environments. (support.microsoft.com)
Consider alternatives if:
You need large visual pointer enhancements (look for pointer highlighting, crosshair overlays, or PowerToys utilities).
You’re on a small laptop without a numeric keypad and don’t want to use Fn overlays or the On‑Screen Keyboard.
You prefer voice, eye‑tracking, or specialized assistive hardware for continuous use. (windowscentral.com)

Final checklist: set up Mouse Keys in under 5 minutes

Open Settings → Accessibility → Mouse (or Control Panel → Ease of Access center). (howtogeek.com, support.microsoft.com)
Turn Mouse keys on and decide whether Num Lock should gate the feature. (howtogeek.com)
Adjust Speed and Acceleration sliders until movement feels natural; enable Ctrl/Shift modifiers for on‑demand speed changes. (howtogeek.com)
Test movement (8/4/2/6) and select left/right using / or -; use 5 to click, 0 to lock drag, . to release. Confirm double‑click pattern on your machine. (support.microsoft.com, windowscentral.com)
If you need to toggle quickly, use Left Alt + Left Shift + Num Lock and confirm the dialog. (computerhope.com)

Mouse Keys is deceptively powerful for a feature that first appeared in classic Ease of Access panels. It continues to serve as a robust, low‑complexity accessibility and emergency fallback tool in modern Windows, now with finer controls for speed and acceleration and keyboard modifiers to handle distance‑versus‑precision tradeoffs. Test it on your system, tune the sliders, and keep the toggle shortcut in your muscle memory — the numeric keypad may be one of the most underrated ways to bring the pointer back under full control when a conventional mouse isn’t an option.
