I'm not sure I'm sold on the "D{0,1}" keybindings. The thought was that 0 would
indicate off and 1 would indicate on. This seems sensible to me. I'm hesitant
because I don't think I have precedent for this idiom in any of my existing
keybindings.
I'm also not sure I like these being leader-prefixed keybindings.
