3:   How do I read topic XXX in the on-line manual?

  When we refer you to topic XXX in the on-line manual, you can read this
  manual node inside Emacs (assuming nothing is broken) by typing this:

    C-h i m emacs RET m XXX RET

  This invokes Info, the GNU hypertext documentation browser.  If you don't
  already know how to use Info, type `?' from within Info.

  If we refer to topic XXX:YYY, type this:

    C-h i m emacs RET m XXX RET m YYY RET

  WARNING: Your system administrator may not have installed the Info files,
  or may have installed them improperly.  In this case you should complain.

  See question 15 if you would like a paper copy of the Emacs manual.
