Vortex.Keymap

Modal key bindings as a theory. A keymap is a script over the Keys row (bind, prefix, unbind); a host folds it onto a KeyNode tree with buildKeymap or applyEdits, dispatches one key at a time with step, and draws prefix popups from infoboxRows. Keys are written Helix-style: space f, C-w, A-x, S-tab, ret, esc, or a printable character.

A host pins the program type in its own wisp-facing module; see Vortex.Keymap.Effects for why.
