By using Home and End, you can change the character color and background color
used to display the file being edited.

Use the Up-arrow and Down-arrow keys to change the character color and 
background color used for highlighted-text. Highlighted text is used to show
marked blocks of text.

Use the PgUp and PgDn keys to change the character color and background color
used for reverse text. Reverse text is used for the status bar and also for
error messages.

If you decide not to use the new settings, press ESC to return to the original
colors. If you want to confirm the color changes you have made, press RETURN,
which changes the colors for the current session. 
The color settings are saved on your disk when you select "Other," then 
"Parameters," then "Save configuration."
