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

595 | where XOFFSET and YOFFSET are positions in pixels from the top left\n\ | |

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

599 | If POSITION is t, it means to use the current mouse position.\n\ | |
600 | \n\ | |
601 | MENU is a specifier for a menu. For the simplest case, MENU is a keymap.\n\ | |
602 | The menu items come from key bindings that have a menu string as well as\n\ | |
603 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
604 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
605 | the keymap as a top-level element.\n\n\ | |
606 | If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.\n\ | |
607 | Otherwise, REAL-DEFINITION should be a valid key binding definition.\n\ | |
608 | \n\ | |
609 | You can also use a list of keymaps as MENU.\n\ | |
610 | Then each keymap makes a separate pane.\n\ | |
611 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
612 | is a list of events.\n\n\ | |
613 | \n\ | |
614 | Alternatively, you can specify a menu of multiple panes\n\ | |
615 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
616 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
617 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
618 | but a string can appear as an item--that makes a nonselectable line\n\ | |
619 | in the menu.\n\ | |
620 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
