PEN*KEY 6400 Windowing Mode
If you try to move the cursor off the display in any direction,
the window shifts one or eight lines or columns in the direc-
tion of the cursor movement. This lets you move the view-
ing window around within the larger VT220 terminal
screen. The display does not wrap when the window reach-
es the top or side boundaries of the virtual VT220 screen. A
beep tone sounds when you try to move the window beyond
a top, bottom, left, or right boundary.
Use the arrow keys in combination with [GOLD] and
[BLUE] to move through the PEN*KEY computer’s display
a single space at a time or eight spaces at a time. The fol-
lowing chart shows key movements.
