8 Help
******

XEmacs 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>.
