      Hi Jody,

      Here is a bit of a refinement of the
      "Toggle Header Status" clip, replacing the boolean tests with
      a bit of math, because we only have two values (1 and 0) and
      ((0+1) MOD 2) returns 1 and ((1+1) MOD 2 returns 0) :

      H="Toggle Header Status"
      ^!Set %temp%=^$GetValue(Clipbook:ShowHeaders)$
      ^!SaveValue Clipbook:ShowHeaders=^$Calc((^%temp%+1) MOD 2)$

      This clip probably runs NO faster than Wayne's original,
      but it's a bit shorter, and shows that there's always
      another way to do things.
