This post explains how to enable or disable 'Use Mouse Keys when Num Lock is On' in Windows 11. Num Lock is the default toggle to activate and deactivate Mouse Keys.

The options for BlockInput are simple. You select which hotkey you want to use to activate the program and how many seconds you want to the application to lock the input from your mouse and keyboard.

If you've longed for more flexibility than the simple on/off method most input control/tyke-blocker programs offer, Kid-Key-Lock gives you finer control over keyboard and mouse use.
