733 POSITION is a position specification. This is either a mouse button event

735 where XOFFSET and YOFFSET are positions in pixels from the top left
736 corner of WINDOW's frame. (WINDOW may be a frame object instead of a window.)

741 MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
742 The menu items come from key bindings that have a menu string as well as
743 a definition; actually, the "definition" in such a key binding looks like
744 \(STRING . REAL-DEFINITION). To give the menu a title, put a string into
745 the keymap as a top-level element.
747 If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
748 Otherwise, REAL-DEFINITION should be a valid key binding definition.
750 You can also use a list of keymaps as MENU.
751 Then each keymap makes a separate pane.
752 When MENU is a keymap or a list of keymaps, the return value
755 Alternatively, you can specify a menu of multiple panes
756 with a list of the form (TITLE PANE1 PANE2...),
757 where each pane is a list of form (TITLE ITEM1 ITEM2...).
758 Each ITEM is normally a cons cell (STRING . VALUE);
759 but a string can appear as an item--that makes a nonselectable line
761 With this form of menu, the return value is VALUE from the chosen item.
763 If POSITION is nil, don't display the menu at all, just precalculate the
