739 in the first pane of the menu, not the top left of the menu as a whole.\n\
740 If POSITION is t, it means to use the current mouse position.\n\
742 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\
743 The menu items come from key bindings that have a menu string as well as\n\
744 a definition; actually, the \"definition\" in such a key binding looks like\n\
745 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\
746 the keymap as a top-level element.\n\n\
747 You can also use a list of keymaps as MENU.\n\
748 Then each keymap makes a separate pane.\n\
749 When MENU is a keymap or a list of keymaps, the return value\n\
750 is a list of events.\n\n\
751 Alternatively, you can specify a menu of multiple panes\n\
752 with a list of the form (TITLE PANE1 PANE2...),\n\
753 where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\
754 Each ITEM is normally a cons cell (STRING . VALUE);\n\
755 but a string can appear as an item--that makes a nonselectable line\n\
757 With this form of menu, the return value is VALUE from the chosen item.\n\
759 If POSITION is nil, don't display the menu at all, just precalculate the\n\
760 cached information about equivalent key sequences.")
