The note tools popover is for manipulating existing notes, not for entering notes. (Well, you can use it to add notes above or below existing notes, but not to enter notes from scratch.) One of the things it can do is change one pitch to another. For example, you can select a range of notes and type a=ab into the popover, and all As in the range will become Ab.
If you wanted this only to affect A4, you could do a4=ab4.
I have a set of notes on my clipboard (e.g. C D E F G) which I convert with python and have M2, M3, P4, P5
I then input a rootnote (in this case C) into Dorico with the caret, exit the caret and press Q to select the chord tool, then shift-I and then paste. Voila, Dorico created them for me!
I also created a way to convert groups of selected intervals into the same octave, using the map pitches popover.
Hi @steinfeld,
just to further clarify: those pitches are only for defining how Inversions will be done (for example to specify the central pitch for inversion) inside the Note Tool popover.
In the newly revised Manual it is much clearer described:
