Change your keyboard language
You must set up more keyboard languages before you can switch between languages. If you set up multiple languages that
use the same keyboard layout (Such as QWERTY, AZERTY, or QUERTZ), your BlackBerry device automatically detects
words in each language.
At the beginning of a new line of text, tap
Tap the language you want to type in on your BlackBerry Keyboard.
If you set up two languages that use different keyboard layouts, the language and default keyboard layout automatically
switches to the other layout. If you set up three languages that use different keyboard layouts, your device automatically
cycles to the next language in the list that has a different default keyboard layout. In both cases, your device recognizes
words from all the keyboard languages you set up.
