Type Alias LayoutKeys 

pub type LayoutKeys<A> = BTreeMap<A, Vec<Chord>>;

One layout’s default keys: every action with its chords in the order the keymap file lists them (at most SLOTS, none reserved), no chord on two actions of one group. The order matters: the first chord is the one help text names, and the chords fill the player’s key slots in this order.
