emacs point-and-click on OSX

[Kevin Patrick Barry]

Dear LilyPond users,

Can anyone provide me with instructions (or a link) to help me get
point-and-click working on OSX? I use aquamacs (i.e. emacs) to edit
lilypond files, and compilation/view works fine, but point and click
still opens the built-in LilyPond editor.  I tried searching for
instructions and found some old messages about it, but they are very
technical and I didn't understand what was involved - a lot of editing
browser options it seems. (I use Firefox.) Right now I'm using the
default pdf viewer (Preview) but I would use a different one if that
would make things easier.  I'm on LilyPond 2.16.2 and OSX 10.9.1.

Thanks in advance,
Kevin
