SXEmacs provides extensive help features accessible through a single character, C-h. C-h is a prefix key that is used only for documentation-printing commands. The characters that you can type after C-h are called help options. One help option is C-h; that is how you ask for help about using C-h. To cancel, type C-g. The function key F1 is equivalent to C-h.
C-h C-h (help-for-help
) displays a list of the possible
help options, and then asks you to type the desired option. It prompts
with the string:
A B C F I K L M N P S T V W C-c C-d C-f C-i C-k C-n C-w; ? for more help:
You should type one of those characters.
Typing a third C-h displays a description of what the options mean; Emacs still waits for you to type an option. To cancel, type C-g.
Most help buffers use a special major mode, Help mode, which lets you scroll conveniently with SPC and DEL or BS.
