1171 | KEYMAP is a keymap. |
1172 | ||
1173 | KEY is a string or a vector of symbols and characters meaning a | |
1174 | sequence of keystrokes and events. Non-ASCII characters with codes | |
1175 | above 127 (such as ISO Latin-1) can be included if you use a vector. | |
bbc4541d | 1176 | Using [t] for KEY creates a default definition, which applies to any |
64239341 | 1177 | event type that has no other definition in this keymap. |
0c412762 | 1178 | |
335c5470 PJ |
1179 | DEF is anything that can be a key's definition: |
1180 | nil (means key is undefined in this keymap), | |
f63fd14e | 1181 | a command (a Lisp function suitable for interactive calling), |
335c5470 PJ |
1182 | a string (treated as a keyboard macro), |
1183 | a keymap (to define a prefix key), | |
f63fd14e | 1184 | a symbol (when the key is looked up, the symbol will stand for its |
335c5470 | 1185 | function definition, which should at that time be one of the above, |
f63fd14e | 1186 | or another symbol whose function definition is used, etc.), |
335c5470 PJ |
1187 | a cons (STRING . DEFN), meaning that DEFN is the definition |
1188 | (DEFN should be a valid definition in its own right), | |
b23916e7 | 1189 | or a cons (MAP . CHAR), meaning use definition of CHAR in keymap MAP, |
00b7c149 RS |
1190 | or an extended menu item definition. |

1761 | KEY is a string or vector, a sequence of keystrokes. | |
1762 | The binding is probably a symbol with a function definition. | |
1763 | ||
1764 | Normally, `key-binding' ignores bindings for t, which act as default | |

0c412762 KS |
1768 | recognize the default bindings, just as `read-key-sequence' does. |
1769 | ||
1770 | Like the normal command loop, `key-binding' will remap the command | |
1771 | resulting from looking up KEY by looking up the command in the | |

1775 | If KEY is a key sequence initiated with the mouse, the used keymaps | |

1777 | and possible local keymaps on strings. | |
1778 | ||
1779 | If the optional argument POSITION is non-nil, it specifies a mouse | |
1780 | position as returned by `event-start' and `event-end', and the lookup | |
1781 | occurs in the keymaps associated with it instead of KEY. It can also | |
