I cannot seem to find it - and more specifically is there one mapped for the magic apple keyboard?
On Windows, its the “<” or “,” key (next to M). I think it would be the same on Mac.
I hope not.
Maybe you mean play from the beginning. I use the dot on the number pad to return to the start and press the spacebar. There maybe a key command for that though. To return and play.
There are no mappings for particular brands of keyboards.
Create your own command macro and assign a keystroke you like.
Beginning of what, you don’t say, so here’s an example to just give you an idea.
