Trimming is also a but of a pain having to select the edit point and then placing the play head where you want the in or out and using another key to trim.
Not sure how one trims without selecting an edit point...but whatever...you can select that edit point with a shortcut, change the edit mode with a short cut and then make the edit with a short cut.
Cant think of any shortcut for Intelligent Playhead Point Selection. ( editors may have to do that for themselves)
