function key support (keys without printable representation) using keyboard macros

 * if enabled, when a function key is pressed it is looked up in Q-Registers ^F...
   e.g. HOME key corresponds to register ^FHOME
 * the string if available is inserted as if it was entered by key-presses
   (later it may be entered as a single input token which may be removed in a single rubout)
 * only NCurses currently, key names directly correspond to Curses key names
 * on Curses if function keys are enabled ESCAPE will be inserted after a delay
   (because function keys are transmitted via escape sequences).
   A function key macro may be used to define an alternative escape character
