I'm working on MC4 for mac and I need help finding a keyboard shortcut. I don't even know what these buttons are called, which is why I provided the image below. It's the diamond-shaped icons to the right of the audio track selectors. Keeping these selected is helpful for keeping synch, especially when extracting/lifting/cutting/pasting. But they keep deselecting themselves as I work on the timeline. Clicking the TC1 diamond selects all diamonds. So I've been trying to find a keyboard shortcut for selecting all diamonds (or whatever they're called). Is there a keyboard shortcut?
