Description#
Default W3C APG menu keyboard policy:
- ArrowRight on a submenu parent that is currently closed →
open-submenu. On an already-open submenu or a leaf item →noop(item-level navigation inside the open submenu is owned by the submenu's own active-descendant). - ArrowLeft when a submenu is open at the current level →
close-submenu. Otherwise →move-to-parent(an enclosing menubar interprets that; a standalone menu trigger treats it as noop).
