I thought it would be nice to make a collection, so people might know other ways to get to programs, etc. in case of certain situations.
Well, there's the obvious..
1. Ctrl + Alt + Delete - Helps exit out of programs in dire situations (Anything else, please add, because I'm sure there's more than that); when you push it twice, it restarts.
2. Alt + Tab - Switches between programs without a mouse.
3. Alt + F4 - Exits out of a program.
