Ctrl+Alt+delete for my work computer so I can go straight to password input.
Space for my home computer.

F3, what else?

I also use Ctrl, or I waggle my mouse to wake both it and my PC (it's wireless).

The first letter of my password.

I giggle the mouse.

I mash the keyboard. It wakes.

Control. I'm mildly paranoid any other key will actually go through and type/do something.

I thump my water bottle down on the desk just hard enough to make my mouse trigger and wake up the PC. By the time I'm sat comfortably it's awaiting a password :]

Right arrow. Wake on mouse disabled because cats. Right arrow is on the bottom right corner and convenient to hit when pulling the keyboard tray out.

Am I the only one that just kind throws my hand on the keyboard and what happens happens?

I slap the spacebar, often multiple times if I'm impatient

If there is a pin set, decimal on the numpad, else Ctrl or ESC.

I just open it.

Arrow up. Multiple times.

The power button

Esc, t, or I move the mouse. Depends on my goal when I'm waking it up.

I use numlok mostly. I guess I’m weird!

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 🤣.
