[Description]
This function performs the Zoom Box command.

[Explanation]
This is the equivalent of the Zoom Box command. After a keypress,
it will display the graph screen. If there is none (i.e. no function graphed), and there aren't
any graphs selected, then you will be presented with a blank screen. If there is a function (or
more) selected, then it will present you with a "dummy axis" (a smaller one).
