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