I am using mouse extender for quite a long time.
I would like to make a suggestion, to create shortcuts for running items within a tab.
So, for instance, the flow would be like:
1. "alt + ~" to show the mouse extender
2. "alt + 2" to select the second tab
3. "5" to run the fifth item (folder / exec) -OR- navigate with arrows and press enter to run the selected item -OR- both :-) .
This would become a great tool for any keyboard user ( we too like graphics :-] ) .
It's really annoying to pickup your hand from the keyboard when you are programming or integrating systems!!
