I have a new Surface Laptop and want to boot to a USB thumb. Unlike the Surface Pro, the laptop does not have a Volume button. It does use F5/F6, but neither work for booting. I know that I can select a custom startup from within Win 10 Pro, but want to go from power off to USB boot. Thanks.
Last night, without any reason, my F4, F5, F6, and Esc keys stopped working. It solved itself, but shortly afterwords it did it again, and even after two reboots I cannot get them to work again. I use hotkeys all the time in Firefox and elsewhere, and these are probably my most-used keys...
