Open containing folder
This is one VS 2008 shortcut I use all the time. Open the folder which contains the file you are currently working on.
Simply right click the tab in the editor view and choose that option. Ok nothing new there. It would be better if there was a shortcut. Go to Tools > Options > Keyboard and select File.OpenContainingFolder and assign a key, I chose Alt+o. Really simple, never got around to assigning it until now.
