12105This is used mainly for mapping ASCII function key sequences into
12106real Emacs function key events (symbols).
12107
12108The `read-key-sequence' function replaces any subsequence bound by
12109`local-function-key-map' with its binding. More precisely, when the
12110active keymaps have no binding for the current key sequence but
12111`local-function-key-map' binds a suffix of the sequence to a vector or
12112string, `read-key-sequence' replaces the matching suffix with its
12113binding, and continues with the new sequence.
12114
12115If the binding is a function, it is called with one argument (the prompt)
12116and its return value (a key sequence) is used.
12117
12118The events that come from bindings in `local-function-key-map' are not
12119themselves looked up in `local-function-key-map'.
12120
12121For example, suppose `local-function-key-map' binds `ESC O P' to [f1].
12122Typing `ESC O P' to `read-key-sequence' would return [f1]. Typing
12123`C-x ESC O P' would return [?\\C-x f1]. If [f1] were a prefix key,
12124typing `ESC O P x' would return [f1 x].
12125
12126`local-function-key-map' has a separate binding for each terminal
12127device. See Info node `(elisp)Multiple displays'. If you need to
12128define a binding on all terminals, change `function-key-map'
12129instead. Initially, `local-function-key-map' is an empty keymap that

4121This is used mainly for mapping ASCII function key sequences into
4122real Emacs function key events (symbols).
4123
4124The `read-key-sequence' function replaces any subsequence bound by
4125`function-key-map' with its binding. More precisely, when the active
4126keymaps have no binding for the current key sequence but
4127`function-key-map' binds a suffix of the sequence to a vector or string,
4128`read-key-sequence' replaces the matching suffix with its binding, and
4129continues with the new sequence.
4130
4131If the binding is a function, it is called with one argument (the prompt)
4132and its return value (a key sequence) is used.
4133
4134The events that come from bindings in `function-key-map' are not
4135themselves looked up in `function-key-map'.
4136
4137For example, suppose `function-key-map' binds `ESC O P' to [f1].
4138Typing `ESC O P' to `read-key-sequence' would return [f1]. Typing
4139`C-x ESC O P' would return [?\\C-x f1]. If [f1] were a prefix
