There is a little more info in the manual:

  A double-quoted string preceded by a dollar sign ($"string") will cause
  the  string to be translated according to the current locale.  The get-
  text infrastructure performs the message catalog  lookup  and  transla-
  tion,  using  the  LC_MESSAGES  and TEXTDOMAIN shell variables.  If the
  current locale is C or POSIX, or if there are  no  translations  avail-
  able,  the dollar sign is ignored.  If the string is translated and re-
  placed, the replacement is double-quoted.

This stack overflow snippet shows the basic usage:

  LANG=foo_BAR.utf8
  TEXTDOMAIN="test"
  TEXTDOMAINDIR="/usr/share/locale"
  echo $"fooMsgid"
  # bash --dump-po-strings <scriptfile>
