== Launch pop-ups on key command? == 

 I really enjoy your popups tool  thanks so much for making it available  but I do encounter two problems with it: 1) it often pops up when I don't want it to, which is annoying, and 2) when I do want it to pop up it takes too long. I thought both of these could be solved with one new feature: a setting where you press a key to cause the pop up. If it was set, no pop ups would appear unless you moused over something and pressed a key (maybe ctrl?). That way, pop ups would never appear by accident and you could cause them to come up as fast as you could hit the control key. 

 I don't think this should be too hard to implement, just replace the current mouseover/timer set up with an onKeyDown thing. In any event, I hope you'll consider it and thanks again for the great tool!
