My memory is a little bit fuzzy, but I was involved in the implementation of the MMB \
and keyboard modifier support. So to add my 2cents.

If the activation was by code (and not by the user.), the keyboardModiefiers() and \
mouseButtons() shouldn't be relevant. And activations by shortcuts should probably \
treated as having no modifier, even if one was pressed. So the action should probably \
emit a signal which has that information tacked on.

konq needs to distinguish various combinations of MMB, Ctrl, Shift on various things \
(bookmarks toolbar/menu, back, forward, home). (Bonus points to anyone who can tell \
me how many different key/mouse combinations are distinguished.)
