The BlackBerry Screen Reader provides a feature called Key Describer mode, which helps you learn
and remember the layout of the keyboard and keys on your BlackBerry smartphone.
To turn on Key Describer mode, press the right convenience key twice and press
any button or key on your smartphone. The BlackBerry Screen Reader will echo the
key pressed and help you create a map of the key layout from memory.
To turn off Key Describer mode, press the right convenience key again.
The Key Describer mode will turn off automatically if you do not press any
key within 10 seconds of turning it on.
