As a user of Superhuman for email, I've come to appreciate the efficiency of keyboard shortcuts and I'd love to have that option as I use Napkin. Here are a few suggestions that come to mind. I'm sure others could add to the list:
- Command+K = list of shortcuts
- C = Compose new new
- S = New Stack
- Tab = tab through notes
- Either T for Tag or L for Label
- / = Search
Those are a few that first come to mind...
