Alt+up/down only works across staves if a note/rest is selected?
I understand "alt+up" and "alt+down" are mapped to commands called "up-chord" and "down-chord", but the curious thing is as long as what's selected is a note or rest they do allow you to jump to the previous or next staff, which is very handy. Is there any reason it shouldn't do the same for other symbols, e.g. clefs or barlines etc.?
In fact even "next-track" (go to next staff or voice, no shortcut key by default) doesn't work as expected for barlines/clefs/time&key signatures - it jumps to the staff below but then to the note/rest following the symbol you were on.
Is there a way you can map a keystroke to a command to change the selection to whatever symbol you're on currently but in the next or previous staff?
