=====Shortcuts=====
Fast ways to create the action:\\

  *Drag and drop a column to a new location.  The //Reorder columns// action is automatically created.
  *To reorder multiple columns at once, select multiple columns and drag and drop them to their new location.  The //Reorder columns// action is automatically created.  (To select multiple columns at once: use Shift+click to select contiguous columns; use CTL+click to select noncontiguous columns.)
