CMD+OPT+L is 3 keys for what will be a very frequent command for me. (I'm a big keyboard power-user, avoid the mouse as much as possible.) It takes both hands and some coordination. How about a secondary shortcut or an easier one, like the Escape key? One or two keys (max), with one hand, easily locatable, and easy muscle memory.
Or will it be possible to customize keyboard shortcuts in a later build?
