About typing input methods
The typing input method that you use determines how you type. For example, if you are using the SureType® input method, even though most keys have more than one letter, you only have to press the letter key for each letter in a word once. Your BlackBerry® smartphone also displays a list of suggested words so that you do not have to type the entire word. If you switch to the multi-tap input method, your smartphone does not display a list of suggested words and you must press a key once to type the first letter on a key and twice to type the second letter on the key.
The language that you are typing in determines the typing input methods that are available. If you are typing in a language that has multiple typing input methods, you can switch between typing input methods when you are typing. When you are typing in certain fields such as password fields, your smartphone might automatically switch your typing input method.
