An apparatus (625) with a first plurality of input keys (635). Some of the first input keys may be associated with both a numeric value and a first set of alphabetic values and arranged in a first alphabetic keypad layout. The apparatus (625) is further provided with a second plurality of input keys (645), positioned adjacent to the first plurality of input keys (635), and being associated with at least one alphabetic value. Some of the input keys of the second plurality of input keys (645) may be arranged in a second alphabetic keypad layout different from the first alphabetic keypad layout. Further, in various embodiments, at least some input keys of the first plurality of input keys (635) have a second set of alphabetic values that is used as part of the second alphabetic keypad layout. Additionally, in various embodiments, at least some of the alphabetic values of the second keyboard layout are arranged at least partially based on a frequency of use of such alphabetic values.
