TINY BLOCK MODE

  In this mode, the screen is treated as a type of graphics mode with a
  resolution of 80x50 - you can't use any text, you can only plot "pixels".
  The cursor keys, <Home>, <End>, etc. move the cursor as explained
  previously. <SpaceBar> will plot a pixel in the current foreground colour
  at the current cursor position.

  Pressing <Shift> with the keys on the numeric keypad will produce a type
  of drawing mode. <Shift>+<RightArrow> will plot a pixel and move the
  cursor one position to the right, <Shift>+<DownArrow> will plot and move
  down, etc. Note that <Home>, <PgUp>, etc. can be used for diagonal move-
  ment.

  As with the normal mode, there are a number of special operations that can
  be performed in this mode. In cases where these functions are similar to
  functions in the normal mode, you will often be refered the corresponding
  documentation for a detailed explanation.
