20. A method of inputting a letter into a device that is capable of supporting at least two modes, each mode displaying one of first and second text areas from which to choose the letter, the method comprising:
-
setting the device into the one of the modes that includes the letter;
inputting a first selecting signal if the letter is included within the first text area of the mode and is initially focused on, inputting a first directional signal to move a focus from a secondary letter to the letter if the letter is included within the first text area but is not initially focused on, or inputting a text area changing signal to display the second text area if the letter is not included within the first text area; and
inputting a second selecting signal if the letter is initially focused on after the input of the text area changing signal, or inputting a second directional signal to move the focus from a secondary letter to the letter after the input of the text area changing signal. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)

28. A method of inputting a command to type a letter into a portable electronic device, which alternately displays one of at least first and second sets of characters one of which includes the letter, the method comprising:
-
inputting a first selecting signal if the letter is included within the first set of characters and is initially focused on, inputting a first directional signal to move a focus from a secondary letter to the letter if the letter is included within the first set of characters but is not initially focused on, or inputting a text area changing signal to display the second set of characters if the letter is not included within the first set of characters; and
inputting a second selecting signal if the letter is initially focused on after the input of the text area changing signal, or inputting a second directional signal to move the focus from a secondary letter to the letter after the input of the text area changing signal.
