   incantation
   spell
      Any particularly arbitrary or obscure command that one must
      mutter at a system to attain a desired result.  Not used of
      passwords or other explicit security features.  Especially
      used of tricks that are so poorly documented that they must be
      learned from a wizard.  "This compiler normally locates
      initialised data in the data segment, but if you mutter the
      right incantation they will be forced into text space."
