shortcut needed

Hi and hello.

I´m new on ardour and really want to get familiar with it!

Please allow 2 first questions:

1.) (desperately wanted!)

I couldn´t find a shortcut for “play range/selection as loop”.
Is there any and if not - how can I create one myself?

2.) Does an ardour forum in german language exist?

Thanks a lot!
Greetings,
