States and behavior
Menu-bar mode, dropdown, delayed pointer submenu, disabled item, check mark, exclusive radio mark and numbered inline MRU group.
Keyboard
Alt alone or F10 focuses the bar; Alt+F/V opens a menu. Arrows navigate; Enter/Space activates; underlined letters select. Escape closes one layer at a time, then exits the bar and restores focus. Tab leaves.
Scope and adaptation
The 1995 draft describes staged menu dismissal and sparse cascades. Short inline MRUs above a separated final Exit match period examples; long/grouped histories may use a submenu. ARIA and the 350 ms pointer delay are explicit browser choices. Ctrl+N is illustrative menu text, not a registered browser shortcut.

Original implementation; system colors are represented by CSS variables. The default 13 px system-font stack is a readable browser adaptation. The 1995 source is preliminary, not a final product specification. Test the target browser and native host before shipping.
