Can you please explain the syntax in the key binding file? I see there is "-" before some commands, what does it mean? And there are some key bindings that repeat themselves (like "space") how does that work? Thanks for the post! Makes me wonder about learning to use Emmet.

Hi Chaim, '-' is usually to override the default command. So that command is longer functioning. And then we bind that shortcut with our own custom shortcut
