1668 | KEY is a string or vector, a sequence of keystrokes. | |
1669 | The binding is probably a symbol with a function definition. | |
1670 | ||
1671 | Normally, `key-binding' ignores bindings for t, which act as default | |
1672 | bindings, used when nothing else in the keymap applies; this makes it | |
1673 | usable as a general function for probing keymaps. However, if the | |

0c412762 KS |
1675 | recognize the default bindings, just as `read-key-sequence' does. |
1676 | ||
1677 | Like the normal command loop, `key-binding' will remap the command | |
1678 | resulting from looking up KEY by looking up the command in the | |
35936c5c | 1679 | current keymaps. However, if the optional third argument NO-REMAP |
b74e16a3 DK |
1680 | is non-nil, `key-binding' returns the unmapped command. |
1681 | ||
1682 | If KEY is a key sequence initiated with the mouse, the used keymaps | |
1683 | will depend on the clicked mouse position with regard to the buffer | |
1684 | and possible local keymaps on strings. | |
1685 | ||
1686 | If the optional argument POSITION is non-nil, it specifies a mouse | |
1687 | position as returned by `event-start' and `event-end', and the lookup | |
1688 | occurs in the keymaps associated with it instead of KEY. It can also | |
1689 | be a number or marker, in which case the keymap properties at the | |
