\b
  Draws a horizontal rule.

\c
  Makes further text centred.

\dDATA\
  Includes inline data in the string. The data is not displayed, but
  can be read by class codes, or used in level titles to provide data
  and delimieters for the auto-generated table of contents. Data items
  are separated by semicolons. (Not fully implemented yet)

\iCLASS:NUMBER\
  Displays a picture. Give the class name (without $ at first) and a
  colon and the zero-based index number of the picture in that class.
  This is then followed by another backslash. The picture may span
  multiple lines; it will automatically move the text to make room.
