Backspace, because my cat likes to step on my keyboard and then characters are often left in the password field that need cleared.

Depends the OS.

Windows its Space

On Linux shift since space will fill in the password field with spaces

Any key

I hit the "wake on lan" icon on my phone, since my computer is in a different room from my monitor and the usb doesn't work for waking it up directly. But if I could, left ctrl all day!

Esc like 3-5 times (to also prompt the login input) or mouse wiggle

The power button. I've disabled usb-wake because my wireless mouse keeps waking up my computer

Escape is kinda hardcoded as a safe button in my headspace and spacebar is just fun to press.

I'm a mad man I click different shit every time.

my computer doesnt go to sleep.

It must stay awake, at all times, awaiting my input.

I plop my furry balls menacingly on the keyboard and inevitably hit at least half the keys

Left arrow up arrow right arrow. over and over and over again until the computer comes up

I push the power button on the tower.

I press my whole hand into the keyboard hitting like 20 keys probably

I have a BLE keyboard and a BLE trackball, so they lose connection when PC is sleeping. To wake it up I press the power button

i rapidly press as many keys as i can within a 1 second time frame

or i just slam the enter key a few times

Caps lock because it doesn't do anything like enter or other keys might do and if I see the light blink then I know that the computer/keyboard is not frozen.

I just stare at it loathfully until it wakes up out of shame.

(Or maybe it's my enraged vibrations transferring to the mouse through the table and causing it to move, same difference.)

Sleep? I run Linux. It's on. Or it's off. So power? I guess?

Power. I'm weird like that, I guess.

My desktop pc doesn't wake up from keyboard inputs, so the power button. On my laptop I just open the lid.

I always hit an arrow key. Just in case it's not actually asleep but just turned off the display, and I don't want to accidentally start typing into something without seeing the screen yet. It's like, 99% unsubstantiated paranoia, admittedly.

I honestly just kind of flop my hand around on the keyboard

If it's suspended I usually open my laptop. If its just locked/screen off I put in my password and press enter because GDM doesn't need to be first "woken up" before entering the password.

So it's "the first letter in my password" which is .....

Ctrl to wake the screen, system set to never sleep. Stupid Plex running on Windows addiction.

I smash the arrow keys like I’m playing a synthesizer.

Mash low in the corner.

Probably a combo of Ctrl-shift-alt-super-z-x-space

I know, much barbarian.

Getting ready for the downvotes… I put my finger on the touch-id sensor of the wireless keyboard.

On my Linux laptops, I usually swipe on the trackpad or track point. If that doesn’t do anything, one of the ctrl keys.

My PC dual functions as a server so it never sleeps

Haven't seen anyone else comment this, I mash all arrow keys

Originally I got into this habit thinking that arrow keys would do nothing, and in most interfaces they don't, but I have learned the hard way they certainly do stuff when watching YouTube.

However it's too late and too embedded in my brain to wake my PC by mashing arrow keys so that is my life

The power button.
