Variable: input-decode-map

input-decode-map is a variable defined in keyboard.c.

Value

Documentation

Keymap that decodes input escape sequences.

This is used mainly for mapping ASCII function key sequences into real Emacs function key events (symbols).

The read-key-sequence function replaces any subsequence bound by input-decode-map with its binding. Contrary to function-key-map, this map applies its rebinding regardless of the presence of an ordinary binding. So it is more like key-translation-map except that it applies before function-key-map rather than after.

If the binding is a function, it is called with one argument (the prompt) and its return value (a key sequence) is used.

The events that come from bindings in input-decode-map are not themselves looked up in input-decode-map.

Probably introduced at or before Emacs version 23.1.
