I just drop my schweaty balls on the keyboard

The only correct answer is num lock. Caps lock is sort of correct, but it's a stupid key on anything that's not a typewriter so I usually disable it so the only correct answer is num lock. No exceptions.

The “touch-id” key that also functions as the power-button.

Spacebar.

First thing I do on any computer that I'm using (work, home) is turning sleep and suspend off. When it's a laptop I disable that closing the lid suspends the laptop. I hate it when I'm moving to a meeting room the thing shuts off. It spins up quickly, but network or whatever is gone, plus gotta unlock it again. Nay.

On other devices, it's moving the mouse first to see if it's not the monitor that went in standby, if that doesn't work I go ham on the spacebar. Finally, the power button if space does nothing, to admit defeat.

My computer never gets the chance to sleep.

Alt

Fn or moving the mouse.

My YubiKey.

If you mean actual sleep, as in S3 sleep, that would be the power button as I disable waking from sleep from anything else as I don't like the PC waking up from accidental keyboard key presses or mouse movements.

If you mean when the monitor goes to sleep, it's the shift key that I mash. Yes, that means on Windows I always have to disable that stupid shortcut to enable StickyKeys.

I make certain to always press a different key every time. I use a keyboard overlay to help keep track, by punching out the key that I just pressed. What happens when I get through them all? First, I cycle through in a unique ordering - by printing off a new overlay ofc - and then when I'm through with that, I know that it's time to get a new keyboard. Btw I'm just kidding, if you couldn't tell 🤣.

Home laptop, power button. Work computer, CTRL-ALT twice brings the login screen.

My PC just never sleeps.

I just change the TV input to PC IN and it's already on.

Any key at the corner. Usually arrow right. It doesn't mess up my password during the time it is waking up where I'm unsure if it is missing one or two characters. Sometimes also [ or control or fn or even backspace depending which keyboard I'm using.

I bang my head of the keyboard so it's random.

Mouse wiggles

Either ctrl or any of the arrow keys

Enter key or space bar

I've always used Ctrl for that. I had my computer for 2 years before I discovered that Ctrl is the "wake from sleep" key, and no other keys would work anyway. (it's a thinkpad)

I don't. I move the mouse.

I was very very very drunk.
