Feature request - keyboard shortcuts

hey guys…small problem with Spark even though i’m using the latest version there is no “keyboard shortcut” to “join selected room”.

I want to automated the login with keyboard login commands to log into 10 rooms at once but with there seems to be no way to automate the “Join room” command eg no keyboard command.

Each time i want to join a room i need to use a mouse to click the “Join Selected Room” icon…this seems kind of dumb…or am i missing soemthing?
Are there undocumented keyboard shortcuts?
