Use the "+NAME" command(key2 & key3) to choose a device name from the device 
list to make it current for processing. Depressing it once will step to the next name
which has the same or higher memory size. Its programming voltage VPP also be shown
on the LCD display.

The "-NAME" command(key1 & key2) works in a similar way, except it goes through
the support list in reverse order.
