Mine is using the arrow keys to navigate typed text while writing and editing. It helps speed things up, versus having to move your hand to the mouse to navigate.
Use the Up and Down Arrows to move/jump vertically.
Left and Right Arrows to move/jump horizontally.
Combine Left or Right Arrow with Shift to be able to select text. Use Up or Down Arrow with Shift to quickly select whole/nearly whole sections of text.
Combine Control with Left/Right Arrow to jump whole words to more quickly move to where you want to type.
Microsoft has never fixed the sticky keys replacement cheese to unlock a PC you have physical access to. Ive done it up to W10, never tested it on W11.
Get a Windows recovery USB.
Boot into the recovery menu and open the command prompt.
Navagate to system32 and make a copy of the cmd.exe file (for a backup)
Copy the sticky_keys.exe and have it overwrite cmd.exe, then reboot.
On the login screen, smash the shift key until the command prompt appears and for some reason (because no user has logged in yet) it has admin permissions, so you can reset local passwords.
Once your logged in as a local admin, copy the backup of cmd.exe back so noone is none the wiser (except the security software that knows you messed with something)
