1396 The `read-key-sequence' function replaces any subsequence bound by
|
|
|
1397 `function-key-map' with its binding. More precisely, when the active
|
|
|
1398 keymaps have no binding for the current key sequence but
|
|
|
1399 `function-key-map' binds a suffix of the sequence to a vector or string,
|
|
|
1400 `read-key-sequence' replaces the matching suffix with its binding, and
|
|
|
1401 continues with the new sequence.
|
|
|
1402
|
|
|
1403 The events that come from bindings in `function-key-map' are not
|
|
|
1404 themselves looked up in `function-key-map'.
|
|
|
1405
|
|
|
1406 For example, suppose `function-key-map' binds `ESC O P' to [f1].
|
|
|
1407 Typing `ESC O P' to `read-key-sequence' would return
|
|
|
1408 \[#<keypress-event f1>]. Typing `C-x ESC O P' would return
|
|
|
1409 \[#<keypress-event control-X> #<keypress-event f1>]. If [f1]
|
|
|
1410 were a prefix key, typing `ESC O P x' would return
|
|
|
1411 \[#<keypress-event f1> #<keypress-event x>].
