For me, it's a question of swapping. I prefer the keyboard but I don't mind working with the mouse. What I can't stand are the poorly designed apps that force you to do both. When I constantly have to switch back and forth between the keyboard and the mouse, I get so frustrated feeling my productivity fall away.

I will however share my all time favorite windows shortcut: Shift-F10

I'll leave it as an exercise for the reader to determine what it does.

Great article by the way.
