I spam escape but I usally disable sleep on all my machines and use hibernation instead. Too many issues with sleep. Randomly wakes up, USB devices aren't recognized, a monitor stays black...
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!
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 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.
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
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 .....
Waking up is hardware encoded to the mouse button, keys are secondary.... It's mentioned on that 'daves garrage' YouTube channel with the guy who was a dev for windows 95.
Control, but I have Caps Lock and my right control key swapped, so physically the Caps Lock key.
It also doesn't really "wake" my computer. When I lock my desktop, I have the operation also set up to enable DPMS with a short timeout, so my monitor also powers down if I'm not typing for a few seconds. When I come back, I just smack Control to make the monitor power on and make my screen locker show an indication that it's active. Unlocking the screen locker disables DPMS, so once the system's unlocked, I don't need to tap anything to wake the monitor.
My machine is dual boot and boots so fast I don't sleep it. If booting to linux, after login it resumes my previous session exactly as it was anyway. No point sleeping it to me.
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 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 🤣.
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.
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'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)
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.
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.
