I have heard of editors using timing information to differentiate
between "<esc>" typed by the user and "<esc>[A" typed via a function
key.  A quickly typed burst registers as a function key hit, a slow
sequence of the same keys registers as a user typed string.  This is
clearly a use of out-of-band signalling via timing information.

I remember hearing about this in the early 80's for an editor on CPM
8080 machines.  Perhaps someone else will recall the exact name of
this editor.
