I gladly use a lot of VS’s shortcuts, and one of my favorites is Ctrl+E, Ctrl+D which will format your document.
Today I missed and typed something else than Ctrl+E, Ctrl+D, causing my editor to show all the tabs as arrows (like in Word). So I had to find how to reset this. In the Edit > Advanced menu I found the correct command (View white space), and if you’re interested in the shortcut: Ctrl+E, Ctrl+S.
