I would first start by reading the Chatterbox FAQ here. The link right there was just created by typing [Chatterbox FAQ], and Perl Monks search is intelligent to locate it directly. It specifically describes all of the things you can link to in the Chatterbox. There are many other things you can link to there, such as:

  /msg                # send a direct message to a fellow monk

  [id://12345]        # Link to node '12345' directly,
                      # showing the original node title as
                      # the text of the link

  [id://12345|this]   # Same, but replace the original node
                      # title with 'this'

  [pad://monk]        # link directly to another monk's
                      # scratchpad

  [cpan://CGI]        # link to the 'CGI' module on CPAN
  [kobe://]           # Kobe search for a Perl module
  [perldoc://]        # Documentation on a perl module
  [jargon://]         # Link to the Jargon dictionary
  [google://]         # Search google for 'string'
  [lucky://]          # "Feeling lucky?" (google search)
  [isbn://]           # ISBN for a book or publication
  [http://]           # Self-explanatory
  [ftp://]            # Ditto, for ftp
  <a href="foo"> </a> # A "normal" HREF link
  /ignore             # Put a user on your ignore list
  /unignore           # Remove a user from your ignore list
  /login              # Log into Perl Monks
  /logout             # Log out of Perl Monks

This should get you started.
