Best new VS Tip - Ctrl +-
Just picked this up from Scott on Writing .
Ctrl +- allows you to navigate through the stack of cursor positions in your VS session. Invaluable when going through multiple F12 (go to definition) in a multilayred application or any comlex debugging session. I expect to use this shortcut daily.
I used to mess around with Ctrl-KK, Ctrl-KN (bookmarks) to achieve the same result. This way is much simpler.
