BlackBerry demonstrated several features said to deliver a best-in-class keyboard experience on either the Z10 or the Q10. Language-processing software that works behind the scenes adapts to the user and the words and language used, according to BlackBerry. Start typing in French and it will understand and appropriately correct misspellings. Switch to German or English and the smartphone will switch, too, without your having to change any language settings. Another feature lists frequently used words in tiny print above letters on the keyboard, as seen above in German, so you can select whole words and add them to a message to speed composition.
