Talking the "Sleep" button...
Back in 2000s, there were some popular cheap external keyboards with three extra buttons between the delete/end/pgdown row, and the arrows.
The first of those buttons was "power off" sitting just below "Delete".

It was pure madness because it was guaranteed to push this button by accident on a daily basis.
I can't imagine someone using computers for more than 5 minutes could have designed this.
We had keyboards like this in several labs in the uni! Except they were even worse, and these three keys were shaped like regular keys. When I accidentally powered down my PC the third time in a row, losing all progress on my assignment, I popped the key out of the keyboard.
when i was a teen the "sleep" button was just right of the enter key so if you slipped, which i often did, night night computer.
