Is there a special shortcut to select to the end (or beginning) of the track?
Shift+End selects the entire project, not just the selected track so it can't be used to create a group for everything to the right of the scrubber.
In the absence of explicit control over the duration of events, I find that I frequently have to group everything and move them over to make space to drag an event's border then move everything back to fill in the gap. Is there some way to select only the events on the track?
