TEXT JUSTIFICATION                                                 <Alt>+J

  This function is used to change the format used to justify text. It can
  be justified, left justified, centered, right justified, or unjustified.
  This function doesn't actually effect the text in any way, to perform the
  actual justification, you must press <F10> when on the line that needs
  justifying.

  Note that any attributes aren't effected by the justification, so you
  should only perform this operation on plain text. Note also that plain
  justification doesn't seem to be implemented at this point in time.
