In addition to sending VT220 cursor control sequences, the
arrow keys at the tops of the keyboards allow you to move
the cursor through the radio terminal’s display. The keys
operate in a local windowing mode, which is enabled with
the black shift or gold shift key. This mode provides a “win-
dow” into the VT220’s screen and allows you to move the
radio terminal’s display window (Figure 4-3). Each key
moves the window in the direction indicated by the arrow.
