B.3.2 Entering Characters
Entering characters utilizes the four CBG control switches in a
similar way to the four arrow keys on a standard computer
keyboard. See Figure B-2. In order to maximize your control
using only four switches, each switch has multiple functions
depending on whether the CBG is in character mode or subset
mode.
Figure B-2: Button Functions
Character Mode In the character mode, scrolling up or down
with switches 1 and 3 will change the highlighted character one
character up or down in the full character set. See Table B-3 on
page B-17.
Subset Mode To make editing the text lines faster, the full
character set is divided into subsets. You can jump from one
subset to the next instead of scrolling through the full character
set one character at a time.
In subset mode, scrolling up or down with switches 1 and 3 will
change the highlighted character one subset up or down within
the list of subsets. See Table B-4 on page B-18.

Hiding Characters If you wish to hide any characters in the
default display, press switches 1 and 3 simultaneously while the
CBG is in subset mode. That character will show in inverse
video and will be hidden from the default display. That character
can still be viewed and changed in the editing mode. A black
background is a hidden character; a white background is a
character that is not hidden.
