! Here we define some reasonable default function key macros.
  Their corresponding command-line editing macros begin with  !

! edit command line to move <n> chars, updating existing move ops !

! Make DELETE an ESCAPE surrogate.
  Macro is enabled everywhere. !
@[DC]{}

! Make SHIFT+DELETE a rubout/re-insert key.
  This reverses the ^G modifier for BACKSPACE.
  The macro is enabled everywhere. !
@[SDC]{}

! Command line editing macros.
  They are enabled only in the start state (i.e. they
  have no effect in string arguments, etc.). !
