At about 13:50 in the video, when you select a bar in the track, "handles" appear in each corner of the bar. When I select a bar, that does not happen... I get no handles, and no way to control the volume. Is there a secret that I missed? *****[EDIT] I was trying that on a MIDI track. Now I've added an audio track, and the method seems to work properly on that track.
I don't believe you can, but at the top of clip view you can tab over from "Sample" to "Envelopes" if you'd like to mute sections of audio right within clip view. But I find it much easier to just shift + tab back to the original waveform to make deletions
