I understand that Dorico has laptop users in mind for its keyboard shortcuts. But there is a plethora of users who got used to input note values, accidentals and articulations with a keypad. Why don’t you give the option to switch the keyboard shortcuts for note entry to “Sibelius” or “Finale”, so the keypad could be used the way we did for years (just the first keypad layout would be enough).
You can do this yourself.
For example, note lengths. Go to Dorico / Preferences / Note Input / Set Note Duration and you can change the Key Commands to match what you’re used to.
