636 If POSITION is t, it means to use the current mouse position.\n\
638 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\
639 The menu items come from key bindings that have a menu string as well as\n\
640 a definition; actually, the \"definition\" in such a key binding looks like\n\
641 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\
642 the keymap as a top-level element.\n\n\
643 If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.\n\
644 Otherwise, REAL-DEFINITION should be a valid key binding definition.\n\
646 You can also use a list of keymaps as MENU.\n\
647 Then each keymap makes a separate pane.\n\
648 When MENU is a keymap or a list of keymaps, the return value\n\
649 is a list of events.\n\n\
651 Alternatively, you can specify a menu of multiple panes\n\
652 with a list of the form (TITLE PANE1 PANE2...),\n\
653 where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\
654 Each ITEM is normally a cons cell (STRING . VALUE);\n\
655 but a string can appear as an item--that makes a nonselectable line\n\
657 With this form of menu, the return value is VALUE from the chosen item.\n\
