simulate each frame using play button in realtime?

[louvfx]

Hi,
Apologies, I can't remember the method to allow tyflow to simulate each frame "one frame at a time'
My work around has been to just create a "typreview' and watch the frames advance one by one without jumping 20 frames at a time.

I remembered being able to do it with the timeline play button, but forgot how to do it.
Frustrating when doing cloth simulations and always having to typreview just to see each frame in realtime.

Thanks!
