I want to make a reference sheet for Emacs. I have several questions:
Are there anywhere definitive cheatsheets on Emacs to base on?
If not, how can i make it myself and how should it look like?
For example, should it be plain text, or PDF, or info file, or .org file, or elisp code?
What would you include in it?
Frequent commands, how to use documentation, common terminology, idiomatic techniques, best practice and nifty tricks, common errors and FAQ, maybe elisp basics?
How to integrate it with Emacs and make it as easy to call as possible?
As cheatsheet is a dense replacement for Emacs manual, it should be easier to consult with, than the manual.
Any ideas and thoughts are welcome.
