Backspace to reduce Indentation Level

Currently on Mac is seems the only way to get out of an indentation level is with a right click.

It would be great if you could just use back space to reduce indentation level just like you can use tab to increase it.

You can use the command key and the square brackets to increase or decrease indent as well. Command—] to indent, Command—[ to reduce.

And actually, shift—tab works to reduce as well.
