So, I'm not completely sure this is the best idea ever but I do find myself trying to switch tabs in VS 2010 using [CTRL] + [1, etc] to switch windows (tabs). Is it possible to configure VS to behave like a web browser causing CTRL+1 switch to the first open window?
The Visual Studio Productivity Power Tools Extension has very similar funcionality:
Tab Behavior More Commands for Navigation (New!)
...
Activate a specific pinned tab by Ctrl+Num Pad 1 through 0
Activate a specific regular tab by Ctrl+Alt+Num Pad 1 through 0
...
