Speed Editor - how to loop play (alt-/) ??

I'm wondering if there's a way to play a looped section directly from the speed editor. Seeing as Resolve has this "unconventional" way of playing looped sections (it requires a special play command) is there an equally complicated and unintuitive way to summon this command from the new Speed Editor?

(Sorry for the sarcasm. I really like a lot about Resolve but some things just baffle me to pieces.)

Thanks!

Double tap the red key.

This functions not. Double click goes only from full window to normal on my system.
