Add a cheatsheet pdf, and latex file

[sh1V1k]

With tools like these I like being able to print a cheat sheet that I can hang by my desk to make it so I don't have to reference the source for common things until it becomes muscle memory. Here I have provided a latex file generated using Claude code for people to modify to their liking as well as a pdf for people who just want one to print out quickly.

I think button ? is good enough for most users.
