Now you have learned a secret about the cursor.
The cursor is not really a little
white
box.. It is just
the inverse of whatever is underneath it. Nor-
mally the cursor is on top of a blank character, so
the cursor appears to be a white square.
Press the CONTROL key and the LEFT ARROW
key several times, until the cursor is on top of the
Kin MAKE.

Now press the D key. Presto! MAKE becomes
MADE, and the cursor moves one space to the
right.
SCREEN 6
Press the CONTROL key and the RIGHT
ARROW key to go back to the end of the sen-
tence.
SCREEN 7
If you try to move the cursor back to the end of
the line by using the SPACEBAR, you will find
yourself erasing characters. Remember this: the
ARROW keys only move the cursor; the
SPACEBAR puts blank characters on the screen.
Take some time now to experiment with the
ARROW keys.
Use the CONTROL key with the RIGHT ARROW
key to move the cursor off the right edge of the
screen. It will wrap around, but it will stay on
the same line.
