Feature request: assignable hotkeys for sequencer editing functions

The sequencer's editing tools have quietly become one of my favorite parts of Pianoteq, especially with the recent addition of "remove events in selection." Continued thanks to the team for that one.

A natural next step would be letting us assign hotkeys to these functions. They currently live only in the context menu, so cleaning up a long, messy take means a lot of right-clicking. Bindable shortcuts would make it possible to build muscle memory and fly through the editing process without losing momentum.

The functions I have in mind:
- remove events before current position
- remove events after current position
- start selection at current position
- end selection at current position
- remove events in selection

No interface changes needed; hotkeys would just be an optional fast lane for power users.

Thanks as always for the consideration.
