I’m stumped in Dorico 3. How does one enter multiple, successive (not stacked) Grace Notes before any given regular note???!!!
Welcome to the forum, Greg.
While in note input, press the slash key, /.
You might benefit from reading my Beginner’s Guide, in addition to the excellent formal resources online. YouTube Dorico channel, online manual, etc.
