A collection of links to useful cheat sheets.

Only what's properly printable can get a spot at the top of this list. It should also be small enough to fit on a few pages.
Almost all links in this document were designed by their creators so that YOU can print them in a good-looking format and store them however is best for you.
Anything that isn't really something you could print in A4/US Letter format, but is still a well-made cheatsheet can get a spot at the end of the page.

Pleae contribute any you remember you've seen and liked.
It would be wonderful if we can get these to be something more commonly made.
