Again for comparison, Blender has a system equally customizable, and further they provide several maps. Two notable ones,“Blender” (default) which is historical, and a little odd frankly, and “Industry Standard” which more closely aligns with other 3D apps (which we all use in our production toolchains). Visual Studio and Jetbrains (programming IDE’s) do the same.
I’m not suggesting Dorico go so far as to have sets (e.g. you could select “Sibelius/Finale/MuseScore compatible” - that would be going too far!), but I don’t think it’s unreasonable to default more commands perhaps. One advantage to doing this is that everybody has a common language, in ‘how-to’ videos, they all use some standard. There are a million Blender how to videos and they all continually call out the key commands, even for obscure operations.
Anyhow either way, just a thought.
