RT3210 Windowing Mode
If you try to move the cursor off the display in any direction,
the window shifts one line or column in the direction of the
cursor movement. This lets you move the viewing window
around within the larger VT220’s screen. The display does
not wrap around when the window reaches the top or side
boundaries of the larger screen. A beep error tone sounds
when you try to move the window beyond one of the bound-
aries.
Paging Through the Display
Use the cursor control key in combination with [FUNC] to
page through the radio terminal’s display. Each corner of
the diamond moves the cursor in that direction.
