Thanks, thats what I was looking for !

One problem I have with this is that it does not seem to automatically 
update the menu when I switch between buffers or frames. I have to run 
"rescan" manaully. I found via a www search that adding

(require 'imenu)
(add-hook 'c++-mode-hook (function (lambda () (imenu-add-menubar-index))))
(add-hook 'c-mode-hook (function (lambda () (imenu-add-menubar-index))))
(add-hook 'fortran-mode-hook (function (lambda () 
(imenu-add-menubar-index))))

to my .emacs makes imenu start automatically, but is there anything I can 
add to make it up rescan automatically ? I found references to a 
`imenu-auto-rescan' variable but since I know next to nothing about lisp, I 
can't seem to get it to work.....
