763 | a definition; actually, the \"definition\" in such a key binding looks like\n\ | |
764 | \(STRING . REAL-DEFINITION). To give the menu a title, put a string into\n\ | |
765 | the keymap as a top-level element.\n\n\ | |
766 | You can also use a list of keymaps as MENU.\n\ | |
767 | Then each keymap makes a separate pane.\n\ | |
768 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
769 | is a list of events.\n\n\ | |
770 | Alternatively, you can specify a menu of multiple panes\n\ | |
771 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
772 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
773 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
774 | but a string can appear as an item--that makes a nonselectable line\n\ | |
775 | in the menu.\n\ | |
776 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
