1760 KEY is a string or vector, a sequence of keystrokes.
1761 The binding is probably a symbol with a function definition.
1763 Normally, `key-binding' ignores bindings for t, which act as default
1764 bindings, used when nothing else in the keymap applies; this makes it
1765 usable as a general function for probing keymaps. However, if the
1766 optional second argument ACCEPT-DEFAULT is non-nil, `key-binding' does
1767 recognize the default bindings, just as `read-key-sequence' does.
1769 Like the normal command loop, `key-binding' will remap the command
1770 resulting from looking up KEY by looking up the command in the
1771 current keymaps. However, if the optional third argument NO-REMAP
1772 is non-nil, `key-binding' returns the unmapped command.
1774 If KEY is a key sequence initiated with the mouse, the used keymaps
1775 will depend on the clicked mouse position with regard to the buffer
1776 and possible local keymaps on strings.
1778 If the optional argument POSITION is non-nil, it specifies a mouse
1779 position as returned by `event-start' and `event-end', and the lookup
1780 occurs in the keymaps associated with it instead of KEY. It can also
1781 be a number or marker, in which case the keymap properties at the
