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

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

SPACE bar

The power button

Win/Super key

I find that pretty safe.

Arrow up. Multiple times.

F3, what else?

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

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.

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

I giggle the mouse.

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

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 :]

I mash the keyboard. It wakes.

I just open it.

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

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

None! And the sucker still wakes up all the time.

I use a arrow key, usually the arrow to the right

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

Shift, Escape and mouse wiggle, in that order.

probably J, since thats where my right hand rests.

click the power button i guess, i forgot.

Right. Mouse. Button.

I will not be taking any questions.

Spacebar sometimes but usually I just smack the keyboard randomly until it wakes up lol
