Helpful for sure except there is still some stuff he does not know. For example he did not know how to nudge events horizontally on the tracks. Here is how:
Nudge Nudging is an alternative to moving Events and notes across the timeline with the mouse. To Nudge any Event or note, select it and do one of the following:
Nudge Press [Alt]+[Right Arrow] on the keyboard to move the Event or note forward in time by the current snap value in the Arrangement or Editor. With Snap disabled, nudging adjusts in milliseconds.
Any number of Events or notes can be selected and Nudged simultaneously. The Nudge commands are also available in the Edit menu.
