658 | This controls the position of the center of the first line\n\ | |

660 | If POSITION is t, it means to use the current mouse position.\n\ | |
661 | \n\ | |
662 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ | |
663 | The menu items come from key bindings that have a menu string as well as\n\ | |
664 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
665 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
666 | the keymap as a top-level element.\n\n\ | |

668 | Otherwise, REAL-DEFINITION should be a valid key binding definition.\n\ | |
669 | \n\ | |
78589e07 RS |

671 | Then each keymap makes a separate pane.\n\ | |

673 | is a list of events.\n\n\ | |
a7ebd443 | 674 | \n\ |
78589e07 RS |
675 | Alternatively, you can specify a menu of multiple panes\n\ |
676 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
677 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
678 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
679 | but a string can appear as an item--that makes a nonselectable line\n\ | |
680 | in the menu.\n\ | |
681 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
