sbt shell: shift+cmd+s does not land me in the sbt prompt Follow

Greetings

I'm a newcomer to the IDEA and use it primarily for scala development. Kudos, by the way... it has been a pleasant flow so far... and after investing some time to learn the shortcuts, that was the icing on the productivity boost :)

I have a small question, however. When pressing shift+cmd+s the sbt shell window is selected, but I need to manually "mouse click" next to the sbt prompt ">" so that I can type commands. Is there a trick to get rid of this mouse interaction?

Again, thanks a lot for a great IDE!

Cheers,
Tanju
