14:  How do I find out how to do something in GNU Emacs?
  
  There are several methods for finding out how to do things in Emacs.
  
  * The complete text of the Emacs manual is available online via the Info
    hypertext reader.  Type "C-h i" to invoke Info.
  
  * You can order a hardcopy of the manual from the FSF.  See question 15.
  
  * You can get a printed reference card listing commands and keys to invoke
    them.  You can order one from the FSF for $1 (or 10 for $5), or you can
    print your own from the etc/refcard.tex file in the Emacs distribution.
    {Are PostScript versions of this available for FTP?}                     +
  
  * You can list all of the commands whose names contain a certain word
    (actually which match a regular expression) using "C-h a"
    (M-x command-apropos).
  
  * You can list all of the functions and variables whose names contain a
    certain word using M-x apropos.
  
  * There are many other commands in Emacs for getting help and information.
    To get a list of these commands, type "C-h C-h C-h".
  
  NOTE: You may find that command-apropos and apropos are extremely slow
  on your system.  This will be fixed in Emacs 19.  If you can't wait that
  long, there is a fast-apropos.el file available in the Emacs Lisp
  Archive (see question 91) that contains the fix.
