next/prev screen lines #2
Description
Bacuse of the limitation of the small size of the screen, the user can miss the first lines of a very long output. This feature will bring "paging" to the programs, by letting the user to "scroll" up and down just like in a man-page on *nix systems, therefore making it possible for the users to read lines which are not accessible right now.
left and/or up keys : move back
right and/or down keys : move forward
q and/or esc keys : quit from paging
