Yes. It stole the idea from that inferior editor, vi. :-)

Does that file look like its got the right data?
To use it, use the `find-tag' function (bound to M-. on my box).
The first time, it will prompt you for which TAGS file to load. the 
default is probably correct. It then prompts for the function name to 
goto. Default is the name at the cursor. So it takes you from the call, to 
the function definition, loading the file if needed.
  After looking at the code, you probably want 'pop-tag-mark' (M-*) to
go back to where you were. Emacs is a great little IDE.

Note also the 'tags-search' function, for doing a global search over all 
source files in a project. And 'tags-query-replace'.

I also have in init.el:

	;; for browsing source code
	(global-set-key 'kp_add 'find-tag )
	(global-set-key 'kp_subtract 'pop-tag-mark )

regards, Mike.
