The big list of cheat sheets

Here is my big collection of cheat sheets that I have collected over the years, around 80± !

In more general usage, a “cheat sheet” is any short (one or two page) reference to terms, commands, or symbols where the user is expected to understand the use of such terms etc but not necessarily to have memorized all of them. Many computer applications, for example, have cheat sheets included in their documentation which list keystrokes or menu commands needed to achieve specific tasks to save the user the effort of digging through an entire manual to find the keystroke needed to, for example, move between two windows.
