Hi!
I wonder why its possible e.g. to click on a lyrics text (shift-l) in order to delete it just by pressing the delete button, but why this is not possible with fingerings. If I click on fingerings both the fingering and the note turn orange. So if I want to delete the fingering I have to open up the popover and delete it there. IMHO thats cumbersome. I mentioned it when I transposed a piece for students from a difficult key (with fingerings) to an easy key, where fingerings became unnecessary.
So the question is: whats the deeper reason, that its not possible to simply click on fingerings and press delete, respectively to double click them in order to open the popover?
Any ideas? Thx!! 
Fingerings are properties of a note. If you want to delete them en masse, select the notes then turn off the fingering property (in the properties panel).
Lyrics are not a property of a note. They are independent objects that can be placed at any rhythmic position, using the caret, even in a bar where there are no notes.
Thanks, I already know how to handle them by popovers. Ok. Properties of a note like articulations. I understand. Thx!
There’s also a menu option for removing fingerings, to which you can assign a key command if you want.
Ok, cool! Thx.
Another question: Dorico knows, that its a fingering for a specific instrument (e.g. brass instruments). Why there is no possibility that the fingering changes automatically when I transpose a piece? Because: the fingerings for e.g. french horns in F are the same worldwide: c=0, c#=12, d=1 …
The simple answer to this is because we haven’t implemented changing fingerings when transposing music. But we’ll perhaps consider this as something for the future.
