Changing the Size of the Cursor
The
CD,
(]J,
00,
and [[) keys will change the cursor size. The cursor,
unchanged, is one unit. You can increase the cursor size up to 19 units in width
and height.
Press the
CD
key and the cursor will become wider. Press the (]J key to
return the cursor to its normal size.
You can also make the cursor taller by pressing the
00
key. To return the
cursor to its normal size, press the [[) key.
Each time you press the
m
or
00
key, two units are added to the size of
the cursor. You may enlarge the cursor up to nine times. The larger the cursor,
the slower it moves around the screen.
Connecting Lines
The
CO
and
CID
keys may be used to connect two points on the screen with
the straightest possible line. Pressing
CID
will cause the computer to remember
the position of the cursor. You may then move the cursor to another point on the
screen without leaving a trail of color.
Pressing
CO
will connect the two points. The
CO
key will also cause the
computer to remember the current cursor position so you can connect it with
the next point. When you connect lines horizontally or vertically, a straight line
is produced. Connecting points diagonally will produce a "lightning bolt" effect.
This comes in real handy when you draw severe thunderstorms.
Filling an Outlined Area with Color
You can use the
m
key to fill an outlined area with the color of the outline.
To use this feature, first draw an outline. Press (CLEAR) to move the cursor inside
the outline. Press
m
and the area will be colored in.
Depending on the shape of the outline, the outline may not be completely filled
with color the first time you use this option. Press (CLEAR) again, and move the
cursor to the area you want colored. Press
m
to complete the coloration.
