Thanks for the replies. The nudge tool helps a lot. The rest is getting acquainted with the editor.
However, the remains one wish: I have a score with a set of identical chords next to each other, but in one of them is a printing error, which is quite difficult to correct.
If it were possible to copy one of the correct chords and paste it over the wrong one, that would be very helpful.
Thanks.
