When the game says ''Press Any Button To Continue'', you press [Button's name].

Alt+F4. Best way to continue :-)

space

Shift or tab

Depends on if I'm holding the mouse or not.
If I'm holding the mouse it LMB, else usually enter, sometimes space.
Plus the mouse doesn't work on all games :/

In keyboard sometimes I press Enter, Space or Esc, in joystick I press Start, Select or A.

I press the power button on my pc.

Whatever button my left hand happens to rest on. Usually S/D/F/shift

I press č, just to test if it's really "any button", because it's not always.

space

space, it has the largets area in my kb

Left mouse button or enter.

I click LMB or enter or space.

space, enter, lmb

The mouse. AND SOMETIMES IT DOESN'T WORK!
Worse is when they want you to press a specific button only. WHY?!

Alt+F4

Alt

DONG

If I'm holding joypad usually I press the "A" Key.On keyboard "Space"

What's up with the super old necros all around? O_o

Random slap of the keyboard here. Least thought/effort required.

Power buttom on my PC and then the PC just shuts down. Oh well ...

Especially the old games usually said "Press A Key".
So I always pressed the "A" key, just because I found it amusing (I'm quite easily amused, you see) :D

I don't press anything, fuck the system!

Space or Enter. I don't know

I press Enter from numpad, sometimes works, sometimes not. Looks like that's not an "any key" ¬¬
