1536 | ||
1537 | Normally, `key-binding' ignores bindings for t, which act as default | |
1538 | bindings, used when nothing else in the keymap applies; this makes it | |
1539 | usable as a general function for probing keymaps. However, if the | |

0c412762 KS |
1541 | recognize the default bindings, just as `read-key-sequence' does. |
1542 | ||
1543 | Like the normal command loop, `key-binding' will remap the command | |
1544 | resulting from looking up KEY by looking up the command in the | |
35936c5c | 1545 | current keymaps. However, if the optional third argument NO-REMAP |

3792 | This allows Emacs to recognize function keys sent from ASCII | |
3793 | terminals at any point in a key sequence. | |
3794 | ||
3795 | The `read-key-sequence' function replaces any subsequence bound by | |
3796 | `function-key-map' with its binding. More precisely, when the active | |
3797 | keymaps have no binding for the current key sequence but | |
3798 | `function-key-map' binds a suffix of the sequence to a vector or string, | |
3799 | `read-key-sequence' replaces the matching suffix with its binding, and | |
3800 | continues with the new sequence. | |
3801 | ||
3802 | The events that come from bindings in `function-key-map' are not | |
3803 | themselves looked up in `function-key-map'. | |
3804 | ||
3805 | For example, suppose `function-key-map' binds `ESC O P' to [f1]. | |
3806 | Typing `ESC O P' to `read-key-sequence' would return [f1]. Typing | |
3807 | `C-x ESC O P' would return [?\\C-x f1]. If [f1] were a prefix | |
3808 | key, typing `ESC O P x' would return [f1 x]. */); | |
