I knew that there was #HJKL navigation and #WASD navigation, and some of the full-screen utilities in the #nosh toolset support both.
I read that there's also QAOP, which alas contradicts the conventional use of 'q' that those utilities already have, and ESDF which alas overlaps WASD.
One cannot be all things to all people, and it seems excessive to make this configurable somehow when they're only limited-use bonuses over just using the normal arrow keys.
