Thanks Daniel and Peter!
I expected that handling this would be given low priority considering other things on the agenda.
I will definitely try mapping custom keyboard shortcuts, at least for the commonly used actions!
Peter, the problem I was experiencing had more to do with how Dorico printed Hebrew text items (e.g. Despite being displayed correctly, a flow title would be printed with the character order reversed). This is possibly a Windows - only issue. A possible workaround for this would be to create the text in an image editor and paste it to the score as an image.
Thanks again.
