APA> I found menu splitting only to work on the top-level. I just found lisp-mode.el to suffer from the same problem. Using M-x find-library RET bytecomp RET M-x imenu-add-to-menubar RET Imenu RET you will notice that the last entry in the "Variables" sub-menu will not even get you halfway down that file. All the other variables cannot be accessed. Is this a known limitation of imenu? Does Emacs not suffer this problem? Thanks for any suggestions, Adrian APA> While I would like to use a sub-menu for functions: APA> (list "Functions" vb-function-definition-regexp 4) APA> this menu does not split and I can only access those functions from APA> the menu that fit on the screen.
