thanks for your reply, but this is not the feature I am searching for.
Part of the problem is Fitt’s Law from a usability perspective. This solution requires first to create a note, then to move my mouse to double, move down without accidentally exiting the menu, and then navigating to the chord I would like to enter. And if you click the wrong one, you have to undo and do the whole thing again.
Besides, the macro only produces root position chords. The described alternative would allow much more advanced options like chord inversions or setting the note length.
Using a mouse wheel to quickly chose a chord does not suffer from fitts law as discrete mouse wheel steps help to find the right chord quickly (if the potential chord is visually represented). You have your chord selected (by default major), click the note, boom! Click another note, boom! If you want to make a minor chord, just scroll one step down with the mouse wheel and click, boom! Scroll to change the length of notes (and see how the note would look like) -> boom!
There is no moving around with the mouse necessary, which makes my wrist happy and it is a lot less error-prone ;)
I would be happy if you could forward this suggestion to your UX team.
By the way, Notion would benefit even more from this feature!
Just because a piece of software can do something in principle, this does not mean it does it the right way. I highly recommend videos like the following. Indeed, this is a very extreme example, but I am sure the Sibelius people made similar "this can already be done" statements:
