CAAD

Occasionally when moving the line at speed it will disappear, this is due to a beat frequency of update
with screen flyback.

Moving the end of the rubber banded line is achieved with:

   Q   W   E
   A      D
   Z   X   C

at 1 pixel per move.  Alternatively use Interface 2 / Plus 2 joystick port 2 or Kempston(tm) interface
(SYMBOL SHIFT & J).

Hold down the CAPS SHIFT key to accelerate to eight pixels per move.

The drawstring editing commands:

Cursor Right      (CAPS SHIFT & 8) - Start of drawstring
Cursor Down      (CAPS SHIFT & 6) - Next command
Cursor Up      (CAPS SHIFT & 7) - Previous command
DELETE      (CAPS SHIFT & 0) - Delete previous command
GRAPHICS      (CAPS SHIFT & 9) - Delete next command

All the following commands require SYMBOL SHIFT to be held down unless otherwise specified.

The toggles:

I   Inverse Toggle
O   Over Toggle
Y   Grid Toggle
J   Kempston(tm) joystick toggle

The next commands all insert into the database:

A   Absolute Move (a PLOT with I and O selected)
B   Block in rectangle attribute area.  Diagonal defined by line.
F   Fill area from end of line.  (See footnote)
G   Gosub to location number with scale
X   Ink (produces prompt for Ink selection)
L   Line fix (draws rubber banded line)
C   Paper Select
P   Plot point at end of line
R   Relative Move point to end of line
S   Shade an area of screen from end of line with pattern
V   Flash Select
Z   Bright Select
T   Text character on screen, selects character and set no.

Note: Fill and Shade are not completely re-entrant.  Fill is a shade with all pixels in pattern set.
