hook for C-Mouse-3?

[Oleksandr Gavenko]

I discover 'imenu' useful with (imenu-add-menubar-index).

But also I like save visible display area by:

(menu-bar-mode -1) ; This switch IMPORTANT for this mail.
(tool-bar-mode -1)

As menu hidden to access menu items I use
C-Mouse-3.

Under 'imenu.el' you can find such code:

(defun imenu-add-to-menubar (name)
...
  (add-hook 'menu-bar-update-hook 'imenu-update-menubar)
... )

so imenu items in menu updated by 'menu-bar-update-hook'
which seems not invoked in menu-bar disabled.

Is there any hook when opened context menu?
