It's actually called the deletion "track".

I don't think we should refer to it as "selecting" words because we're not
selecting words anymore. We only move the cursors.

So maybe "MovesPerSwipe" might be a better name. Need to update the description
to describe a "move" as moved past one word.

ditto above with "deselect". BackwardsMovesPerSwipe instead?
