Context: I'm working on a WPF application where the user often has to transcribe bits of data manually from other programs. Not having dual monitors, this involves a lot of Alt-tabbing. I figured that it would be quite nice to have the same functionality as in Visual Studio for tooltips - where you can hit Ctrl to render them slightly t...
