shift modifier

The shift modifier key is a core part of Windows accessibility and keyboard-driven workflows. In Mouse Keys, holding the Shift key while pressing a numeric keypad direction key accelerates pointer movement, while the Ctrl key slows it down for fine control. This modifier behavior lets users adjust cursor speed on the fly without opening settings. The shift modifier is also used in other Windows keyboard shortcuts and accessibility features to extend or modify default actions. Understanding how the shift modifier works with Mouse Keys helps users who rely on keyboard-only navigation or need precise pointer control when a mouse is unavailable.
