Re Indent a whole page in Sublime Edit 3 with Key Binding

In Sublime Edit 3, I got fed up of having to go to the Command pallet ever time I want to re-indent my file. To apply a key binding;

Go to Preferences -> Key Binding – User

Enter this into the file.

[
	{"keys": ["control+shift+i"], "command": "reindent", "args": {"single_line": false}}
]

If you already have one or more shortcuts in this file, simply append a comma to the last “keys” entry and past the keys line in.
