markings. Some keys have blue markings, and
others have both. For example:

The keys with the black markings work as
labeled when you are using a personal computer,
a host computer, or a note pad session, o! when
controlling your work station in control mode.
In general, the keys with the blue markings work
as labeled when you are working with a PC
session.
The keys with both black and blue markings
work in two ways:
1. The blue markings work only in a PC session.
2. The black markings work everywhere else.
