Thoughts
My favorite part of "Info: An Introduction" is when instead of saying, "press space to scroll down and delete to scroll up" it says:
> The SPC, BACKSPACE (or DEL) and b commands exist to allow you to “move around” in a node that does not all fit on the screen at once. SPC moves forward, to show what was below the bottom of the screen. DEL or BACKSPACE moves backward, to show what was above the top of the screen (there is not anything above the top until you have typed some spaces).
> >> Now try typing a SPC (afterward, type a BACKSPACE to
return here).
> When you type the SPC, the two lines that were at the bottom of the screen appear at the top, followed by more lines. DEL or BACKSPACE takes the two lines from the top and moves them to the bottom, usually, but if there are not a full screen’s worth of lines above them they may not make it all the way to the bottom.
