-MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\
-The menu items come from key bindings that have a menu string as well as\n\
-a definition; actually, the \"definition\" in such a key binding looks like\n\
-\(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\
-the keymap as a top-level element.\n\n\
-You can also use a list of keymaps as MENU.\n\
- Then each keymap makes a separate pane.\n\
-When MENU is a keymap or a list of keymaps, the return value\n\
-is a list of events.\n\n\
-Alternatively, you can specify a menu of multiple panes\n\
- with a list of the form (TITLE PANE1 PANE2...),\n\
-where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\
-Each ITEM is normally a cons cell (STRING . VALUE);\n\
-but a string can appear as an item--that makes a nonselectable line\n\
-in the menu.\n\
-With this form of menu, the return value is VALUE from the chosen item.\n\
-\n\
-If POSITION is nil, don't display the menu at all, just precalculate the\n\
-cached information about equivalent key sequences.")

+An ITEM may also be just a string--that makes a nonselectable item.\n\
+An ITEM may also be nil--that means to put all preceding items\n\
