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.)
