dscreen Select keys

When a new virtual screen is created, it is assigned a select key.

Pressing the select key causes the following actions:

• A switch from the physical terminal to the video page associated with the particular virtual screen.
• Input and output is directed appropriately between the physical terminal and the virtual screen.

After all of the select keys defined in the dsinfo file have virtual screens assigned to them, no more screens can be created. Individual screen sessions end when the original shell process exits. This frees the associated select key for use with another virtual screen. The dscreen utility is ended when there are no more active screens.
