743 corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.)
744 This controls the position of the center of the first line
745 in the first pane of the menu, not the top left of the menu as a whole.
746 If POSITION is t, it means to use the current mouse position.
748 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
749 The menu items come from key bindings that have a menu string as well as
750 a definition; actually, the "definition" in such a key binding looks like
751 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into
752 the keymap as a top-level element.
754 If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
755 Otherwise, REAL-DEFINITION should be a valid key binding definition.
757 You can also use a list of keymaps as MENU.
758 Then each keymap makes a separate pane.
759 When MENU is a keymap or a list of keymaps, the return value
762 Alternatively, you can specify a menu of multiple panes
763 with a list of the form (TITLE PANE1 PANE2...),
764 where each pane is a list of form (TITLE ITEM1 ITEM2...).
765 Each ITEM is normally a cons cell (STRING . VALUE);
766 but a string can appear as an item--that makes a nonselectable line
768 With this form of menu, the return value is VALUE from the chosen item.
770 If POSITION is nil, don't display the menu at all, just precalculate the
771 cached information about equivalent key sequences. */)
