If you want to insert, change or edit chords and texts, you can of course also do this in Score and e. g. in the Note Editor.
In the note editor, you can enter a karaoke text by pressing the K button. Or with the C7 button the chords.
If you have inserted a text or chords with these functions, click on the note and the syllable or chord will be inserted below or above it.
For smaller changes, an existing text or chord can also be edited directly in the note view.
Double-click the chord or syllable and change it.
