FVWM: popup-menu question

[Glen Lee Edwards]

In a Menu, or a Popup-menu, is there a way to set them up so when the 
mouse focuses over one of the options that you can get a different 
response based on which mouse button you press?

For example, on my popup-menu, if I scroll down to an item called "Web 
Browser", is there a way to set it up so that if I left click I open Ice 
Weasel, center scroll button click opens Opera, and right click opens a 
sub-menu of bookmarks that I have configured in .fvwmrc?
