(info "(elisp)Tool Bar") describes how to add modifiers to the fake
function keys in the tool bar, but really the following sample code
has no effect:

  (define-key tool-bar-map [S-help] 'info)

I think only mouse-1 should not popup menus, but in many modern
applications mouse-3 is a standard way to show a popup menu
with a complete list of items related to the main item invoked
via mouse-1.
