On Windows operating systems you have a set of macros that automatically execute commands/functions.

Here are a few of them.

Spoiler:

Crtl + V = Paste
Crtl + X = Cut
Crtl + C = Copy
Crtl + Z = Undo
Crtl + Y = Redo
Crtl + Shift + S = Save As
Crtl + S = Save
Crtl + Alt + Delete = "Shutdown" without shutting down.
Shift + [letter] = Upper/Lower inversion of letters.
Shift + [number] = Number inversion, ex: 3 = #
F2/F11(Depending on OS) = Access BioS (On startup only)
F5 = Reload website (In-browser only.)
F11 = Full screen mode.
Tab = Four spaces.

That's all for now until I get ungrounded.

Alright, this is useful I guess.

Thanks.

Is this not extremely common knowledge already?

[3SidedSquare]

I'm with Eminem, I use crtl + c,v,s,z on an hourly basis; and the shift key with any combination of other keys probably a few times per minute.

I think the only people that need this are the elderly.

Spoiler:

Your description of the tab key is far from accurate.

[w00t]

Tab isn't 4 spaces on Windowns, it's the tab character( 0x09 ). Certain applications will let you change that behaviour, which you should do if you want to contribute code to any FOSS.

I can't tell if you're being serious or not.
