  AML Function Quick Reference
  ────────────────────────────
  This Quick Reference lists all AML statements and functions and by
  category, including builtin (A.EXE), library (LIB.X), and extension
  (EXT.AML) functions.

  To use the Quick Reference within a macro: move the cursor to a
  function name or statement keyword and press <shift f1>. This Quick
  Reference can be used in any text file, including the Language
  Reference (LANGUAGE.DOX), and the Function Reference (FUNCTION.DOX).

  To transfer to the full AML Function Reference: move the cursor to a
  function name or statement keyword in this Quick Reference and press
  <shift f2>. Note that most extension functions are not documented in
  the Function Reference.
