Lock Keyboard & Screen for Cleaning

[rabbly]

Challenge
Cleaning screen & keyboard is difficult - as you need the screen to be black and when cleaning the keyboard you accidentally press buttons.

Solution
Have a toggle that makes the screen black, and locks the keyboard, until you use your mouse/trackpad to click on "Unlock".

Note - OneSwitch has similar capability for reference.

Nevermind, already available! Use the "Screen Test" feature (perhaps renaming or a help text for that would be useful)
