Looking for some shortcut help- I thought I would remember haha.

I am trying to recall how to render a small selection of the movie in real time. I think I watched it on a Douglas Spotted Eagle session and it was something like make my selection, then ctl+shift+g (something that quick) and then it rendered quickly that section and played it realtime and kept looping that selection until I stopped it.

It would make my life much easier if someone had the trick.

thanks
