If you're happy to actually run the program, you can do even better
using SLIME. I've got the following code in a file called
~/.maxima/startswank.lisp:
(require :swank)
(swank:create-server :port 56789 :dont-close t)
Then if I start Maxima and run load("startswank"), I'll create a socket
to which SLIME can connect. Now connect to it with M-x slime-connect
Once all this is done, M-. will work through SLIME and will query the
running lisp process to ask it where a function or variable was
defined. This is somewhat more robust than using a tags file. Even
better, if you're writing some code in lisp, you get clever tab
completion, arguments echoed in the minibuffer etc. etc. It's really
good!
