But wait; there's more!

As indicated at the beginning, this is not a complete reference manual. It has not covered scrolling sideways, tab setting, the mail system, the Emacs internal Lisp dialect, automatic abbreviation, the spelling checker, the directory editor, the change-log editor, or how to replace all groups of lines of your program that are indented more than ARG spaces by `$\ldots$'¹. You can learn about these and other topics by using C-h i. You might also try typing C-h f SPC C-x o C-x o, which creates a buffer containing the names of all Emacs functions and then puts the cursor there so that you can scroll through and look for likely-sounding names.

Just use it. Every session is an adventure.
