Google search for how to move a note up or down an octave leads here
The note in question is highlighted orange. However, Ctrl-Alt-Up Arrow doesn’t work, although it accomplishes the neat office trick of flipping my Windows desktop view upside down.
So then I thought ‘let me map my own key command’. I pressed Ctrl-comma to bring up the Preferences and found the spot where Octave Up and Down are. I tried various keyboard shortcuts but none of them worked.
I then searched this forum itself for a while and found this page
I then realized that maybe it matters whether I invoke the command before or after inputting the note. I have been trying to change the octave of a note that I already input. So I decide to go back to the preferences and see if I can look around.
But this time, Ctrl-comma does not open the preferences box!! Still in Write mode, just like before.
At this point (after the slur thing yesterday), I have to ask - it possible that there is some sort of incompatibility with my keyboard (Corsair Vengeance K60) and the software?
