In any windows system this happens:

- show your desktop

- move your mouse over an icon

- keep pressing 'home' on your keyboard (home key brings the focus to top left icon) and then left mouse button (changes the focus to the icon you're over)

- do it faster and faster (home, lmb, home, lmb, ...), focus will jump between top icon and the icon under the mouse pointer

- when you reach the double-click speed, the icon will be launched

but it will not be the icon under the mouse pointer, but the top left corner icon.

Ok, this is legit. Blew my mind.

I've discovered it in like 1998, but I waited for a good moment to reveal it :)

Keyboard driver's usually more responsive. Hence why this makes sense.
