The new Team Explorer in Visual Studio 2012 has taken me some getting used to.
When working with source control in VS2012, there is no longer a ‘Pending Changes’ View that is independent of team explorer. I missed it because now I must navigate 3 menus into Team Explorer to find out what files I have modified.
That was until I found the new Solution Explorer filters. Pressing Ctrl+[, Ctrl+P will filter the solution explorer to show only checked out files. Tap again to remove the filter. Sweet!
Another interesting shortcut is Ctrl+[, Ctrl+O that filters solution explorer to show only files you have open
