Auto-format key binding in Sublime Text 2

This mapping has saved me tons of time in Sublime keeping my code organized and readable:

{ "keys": ["ctrl+shift+r"], "command": "reindent" , "args": {"single_line": false}}

You can map this binding by clicking on the "Preferences" tab and selecting "Key Bindings - User."
