630 | POSITION is a position specification. This is either a mouse button event\n\ | |

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

636 | If POSITION is t, it means to use the current mouse position.\n\ | |
637 | \n\ | |
638 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ | |
639 | The menu items come from key bindings that have a menu string as well as\n\ | |
640 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
641 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
642 | the keymap as a top-level element.\n\n\ | |
a7ebd443 RS |
643 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.\n\ |
644 | Otherwise, REAL-DEFINITION should be a valid key binding definition.\n\ | |
645 | \n\ | |
78589e07 RS |

649 | is a list of events.\n\n\ | |
a7ebd443 | 650 | \n\ |
78589e07 RS |
651 | Alternatively, you can specify a menu of multiple panes\n\ |
652 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
653 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
654 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
655 | but a string can appear as an item--that makes a nonselectable line\n\ | |
656 | in the menu.\n\ | |
657 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
658 | \n\ | |
