As long as you type no characters, you can press
RETURN to put space between lines of text. Try
pressing RETURN a few more times.
SCREEN 3
Now the cursor is getting closer to the bottom
of the screen. We have seen that the cursor will
wrap around horizontally. Will it wrap around
vertically, too? Keep pressing the RETURN key
until the cursor reaches the bottom of the
screen.
SCREEN 4
Now press RETURN a couple more times. In-
stead of the cursor moving, the whole screen
moves up. The top lines get shoved off the
screen and cannot be retrieved.
SCREEN 5
If you keep pressing RETURN you get rid of all
the lines on the screen. Moving lines up off the
screen in this manner is called scrolling.
