4.3 Screen navigation
Navigation is accomplished by using the Up/Down Arrows and the
Enter Key. The NS3 responds to two types of key depression, “tap” or
“hold.” “Tap” commands are completed by depressing the key for less
than one second, while “hold” is for depressing the key for more than
one second. Key use is further dened in the table below.
