Probably stupid but... (+25 rep!)

To some of you this might be a dumb question, but, why do shortcuts like Ctrl+V (Paste) etc, work for me :s

they work for everyone lol.

i use control & A alot to "highlight all" everyone can use them as far as i know.

Because they're like that on every computer.

Its designed to :s

because that's how a pc works.

Because it's just how a shortcut works.

I think it's Built in with Microsoft or Other Company's When you download windows Ect..

should work for every pc

As others have said, it works for everyone, on loads of different computers.
