Trigger tear off menu by desktop right-click?

This was the best I could do. Excluding mozilla was important not to lose mouse gestures that are started with rightclicks in firefox.

Code:

SetTitleMatchMode, 2


#IfWinNotActive, ahk_class MozillaUIWindowClass
RButton::
MouseGetPos,,,winid
WinGetTitle, wintit, ahk_id %winid%
If wintit= Program Manager
    Send, ^q
else
    send {RButton}
#IfWinActive

return

I'm using desktop icons, but most of the time -also on the screenshots- I hide them using stardock fences.
