A few menu keyboard shortcuts are missing. How about:

<ctrl>W for close window
<ctrl>Q for close all windows
<ctrl>O for Options manager
<ctrl>D for Download manager
<ctrl>Z for Undo close window
<ctrl>R for Reload page
<ctrl>I for show images

Also, please add the toolbar menu as a submenu of the main menu (maybe in Tools submenu), so it will be accessible by the menu key.

A patch including all these changes is at:
