If you could use one computer function in real life...

[headshotcatcher]

Control + Z, anyone who thinks otherwise is silly (you can do whatever you want with Undo)

 

[flare09]

Console, noclip.

 

[razbuten363]

The Console...I'll be like God

 

[thiosk]

right-click to open context-sensitive menu

fuck you macintosh

 

[Cortheya]

Control F...I could find anything in the world
That or copy paste

 

[sgtshock]

Ctrl-F, Ctrl-Z, and noclip. If only.

 

[Ushario]

while(!asleep)
{
++sheep;
}

Depends on how high level the function is allowed to be, since command console isn't a function and it is part of an application...I'm just here to ruin your fun! Bwahahaha

 

[N0b0dy]

run cheat engine

 

[ICantBelieveItGoesBoom]

Delete would be infinitely useful.Why?

I CAN DELETE TWILIGHT!!! And Stephenie Meyer, Hannah Montana, the Jonas Brothers, Jack Thompson, Uwe Boll... oh yeah, Fox News too.

Oh yeah, , ,AND HUGH JACKMAN!

Cookie for the reference.

 

[rockingnic]

Delete.

 

[Predlin]

one word. savestates

 

[Harlemura]

Alt+F4
I wouldn't have to get up to close the windows!

 

[Rensenhito]

"Escape"(Damn schooltests) and "Insert"(Cookie if ya get it XD)

Consider it gotten.
I'm gonna have to go with Quicksave / Load or System Restore. Who wouldn't want to have infinite tries at life?

 

[ExistentialCrisis]

Save As Desktop Wallpaper

You could change your appearance at will with that, I imagine. Just picture the possibilities...

...even though sometimes you might accidentally click it on a .gif and you end up Tiled with a repeating animation loop...or on a tiny 45x60 image and it gets all Stretch'ed out and heavily pixelated on you...

 

[Pimppeter2]

sorry wrong thread

 

[DragonChi]

the ability to store TB's of memory with easy access. I have bad short-term memory.

 

[okwhat]

I would use Undo, so I could undo the night that I got caught and arrested for underaged consumption. Cause now my summer is filled with dread since I've got to go to court sometime in the near future. FUCK.

 

[Xender90]

Ctrl Z

 

[Nightflight51]

Ctrl + F4
I would turn off the universe.

That, or copy and paste. I'd never go hungry.
