You can post a menu from the keyboard by typing Alt+x, where \"x\" is the character underlined on the menu.  You can then traverse among the menus using the arrow keys.  When a menu is posted, you can invoke the current entry by typing space, or you can invoke any entry by typing its underlined character.  If a menu entry has an accelerator, you can invoke the entry without posting the menu just by typing the accelerator."
