Move notes within the key signature with arrow keys

Hello. My feature request is that there be an option to be able to move notes within the key signature using the arrow keys. I think that the current behaviour (moving by half steps) should be kept, but this option should be added. When I say "move within the key signature," I mean that notes should move a whole step up all the time except when moving between the two half steps in the scale. This is the exact same behavior as in Sibelius. In D Maj, for example, it would move from d, to e, then f#, g a b c# d. There would be no accidentals.
