There are several newish key commands in the game. I whipped together a quick Help page (which will be fleshed out more in the future) that lists them. See top right navigation. This will be edited and added to as we go.
The best ones, in my opinion, are the three that make your character show emotions. But, the cmd-enter or ctrl-enter to enter/exit the chat pane are also perty handy.
Any other common functions that you'd like to see quick keys for?
