(In Info, you only see this section if your terminal has a small number of lines; most readers pass by it without seeing it.)
Since your terminal has a relatively small number of lines on its screen, it is necessary to give you special advice at the beginning.
If you see the text --All---- near the bottom right corner
of the screen, it means the entire text you are looking at fits on the
screen. If you see --Top---- instead, it means that there is
more text below that does not fit. To move forward through the text
and see another screen full, press <SPC>, the Space bar. To move
back up, press the key labeled Backspace or DEL (on some
keyboards, this key might be labeled Delete).
