706 | You can also use a list of keymaps as MENU.\n\ | |
707 | Then each keymap makes a separate pane.\n\ | |
708 | When MENU is a keymap or a list of keymaps, the return value\n\ | |
709 | is a list of events.\n\n\ | |
710 | Alternatively, you can specify a menu of multiple panes\n\ | |
711 | with a list of the form (TITLE PANE1 PANE2...),\n\ | |
712 | where each pane is a list of form (TITLE ITEM1 ITEM2...).\n\ | |
713 | Each ITEM is normally a cons cell (STRING . VALUE);\n\ | |
714 | but a string can appear as an item--that makes a nonselectable line\n\ | |
715 | in the menu.\n\ | |
716 | With this form of menu, the return value is VALUE from the chosen item.\n\ | |
