14 Introduction
If the current page or portion of the page is longer than the screen display or window in
which it is displayed, then local keystrokes can be used to “pan” the window up or
down (
Ctrl- ↑ and Ctrl- ↓ ). As a window is panned up, the page appears to be moving
down and the opposite is true when panning the window down. Text that is panned
off the screen is out of view, but is not lost.
The figure below represents the display screen with a 48 line page length on a 44 line
screen, after panning the window down 2 lines.
