menu selection. Press and release one edge of the key to move the display screen one line
or one character in the direction of the arrow.

name, password, and domain name. Microsoft’s definition includes some wireless network
IDs as equivalent to SSIDs.

RAM (random
access memory)
You can add applications and data files to RAM or into Flash memory via the
FlashFX
Disk. While Flash memory is persistent (as long as the backup battery is charged), RAM is
not and will be cleared when you remove or replace the battery. As you can only suspend
the device, the only way to turn it fully off is to remove the battery or to perform a cold reset.
