  728. \makeescape, ..., \makecomment allow users to change category
  729. codes a little more easily.
  730.  
  731. \savecat#1 and \restorecat#1 will save and restore the category
  732. of a given character.  These are useful in cases where one doesn't
  733. wish to localize the settings and therefore be required to globally
  734. define or set things.
  735.  
  736. \SaveCS#1 and \RestoreCS#1 save and restore `meanings' of control
  737. sequences.  Again this is useful in cases where one doesn't want to
  738. localize or where global definitions clobber a control sequence which
  739. is needed later with its `old' definition.
  740.  
  741. Abbreviations.  Just a listing with indications of expansion where
  742. that may not be obvious.  For full definitions, see real code above.
