Some of the commands I use the most are buried kind of deep. I just got a Stream Deck and am happily assigning key commands like crazy, but sadly, there are a few commands which aren’t available in the key commands section of preferences:
wish list:
Select to end of system
Select to end of flow
Filter->notes in chords->Top notes or single notes, second note, third note, etc.
OR if there were a hotkey to open the top level EDIT menu, I could assign keystrokes to get to the aforementioned menu items.
As Dan says, you can already assign shortcuts to both Select to End of System and Select to End of Flow. You will be able to assign shortcuts to the “notes in chords” filters in the next big update, too.
