Intro to Emacs
Emacs is a wonderful, powerful text editor, but it can take some getting used to. Here are some of the commands you need to know to go from n00b to a text-editing ninja:
Taken from my answer to this question
Key: C = Ctrl, M = Esc. (Protip: if you are a heavy emacs user, switch your caps lock key to an esc key to make the commands a lot easier)
Basic Text Editing C-space: set mark C-w : Cut M-w : Copy C-y : Paste C-x s : save C-x c : save all and close
Navigating Through a File
M-b : back one word M-f : foward one word C-f : forward one character C-b: backward one character C-a : beginning of line C-e : end of line C-n : next line C-p : previous line M-< : beginning of buffer M-> : end of buffer
Using Multiple Files
C-x C-f : find file C-x b : switch buffer C-x k : kill buffer C-x 2 : split-window-vertically C-x 3 : split-window-horizontally C-x o : switch window C-x 0 : kill this window C-x 1 : kill all other windows
Other Handy Commands
C-s : search C-r : search backward M-/ : autocomplete word (based on previous words in the file) C-x ( : start keyboard macro C-x ) : end keyboard macro C-x e: execute keyboard macro.
C-h: help C-h f: describe function C-h k:describe key
but this is just scratching the surface. If you have any other questions about using emacs, feel free to ask!
