I would love a "Go To START Marker" keyboard shortcut. As far as I can tell there are options to jump to 0, or to restart playback from START every time you hit stop/play, but I usually don't want to jump back EVERY time. If I'm in the middle of a mix and have made a change, I occasionally want to immediately jump back to START to play from the beginning. It's achievable now through two mouse clicks, so not terribly inconvenient. But a "go to START" keyboard shortcut option would be great.
