GNU Emacs has excellent help facilities. Most of them are accessed
with the prefix C-h
. The Emacs tutorial is an interactive introduction
you can work through fairly quickly to learn the most common key
bindings. C-h i
accesses the GNU hypertext info browser from within
Emacs, displaying system info pages (including the Emacs manual
itself). Here are some of the help-related key bindings:
C-h t | Emacs tutorial |
C-h i | Load info browser |
C-h m | Display help on current mode |
C-h f | Display help on function (Emacs prompts for function) |
C-h k | Display help on key (Emacs prompts for key) |
M-x man | Display a man page in a new buffer (Emacs prompts for man page) |
