Use the SPACE bar to stop the preview
I create Doodly videos that have to sync to voice-overs, and because of reasons, the sound is made before the animation. So getting the timing right is working constantly on it for different elements. So I constantly preview the scene to see if it has to be 1.25 or 1.5 seconds. I monitor it (I would REALLY like a short key for a scene preview, like command-P) and when it is off, I would like to hit a key, to go back to the time asap. Having to actually close the preview window seems not logical in the workflow of getting the timing right.
Being able to just hit a short key for a scene preview, and another to close it (could be the same), would really help to get things right, without too much moving the pointer around and stuff.
