I find that the cursor keys are too fined grained when I need to jump in steps to the left or right of the play bar. In some editors, shift left cursor moves in a large step, ctrl left cursor moves in a larger step and alt cursor moves in an even larger step. This would be so useful when you want to jump to the beginning of a word that you want to silence (I can't delete as I edit video sound tracks and sound would be out of sync) To have to hold the cursor key down or press + and - repeatedly to zoom in and out is frustrating and annoying.

Kind regards
