When creating an e-mail or text message on your device, you can use the number keys to enter letters, numbers, punctuation, and symbols such as emoticons.
You can enter text in what is called “Abc mode” by pressing each key until the letter you want appears on the screen. For example, to enter the word "shoe" in Abc mode, you would press 7 four times, 4 three times, 6 three times, and 3 two times.
On some mobile devices, you can use what is called “T9 mode” to enter whole words. T9 stands for "text on 9 keys." This function may let you enter text faster than other methods.
As you press each key in T9 mode, the device analyzes the possible letters associated with that key and attempts to predict and complete the word. For example, to enter the word "shoe" in T9 mode, you would press the keys 7, 5, 6, and 3 once each, scroll to the word “shoe” in a list that appears, and then press ENTER.
