695 | If POSITION is t, it means to use the current mouse position.\n\ | |

698 | The menu items come from key bindings that have a menu string as well as\n\ | |
699 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
700 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
701 | the keymap as a top-level element.\n\n\ | |
702 | You can also use a list of keymaps as MENU.\n\ | |
703 | Then each keymap makes a separate pane.\n\ | |
704 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
705 | is a list of events.\n\n\ | |
706 | Alternatively, you can specify a menu of multiple panes\n\ | |
707 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
708 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
709 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
710 | but a string can appear as an item--that makes a nonselectable line\n\ | |
711 | in the menu.\n\ | |
712 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
