A keyboard for a mobile communication device includes a first set of alphanumeric keys that is arranged in a two column by three row array. In a first example, the key arrangement includes vowels and consonants in the two by three array, with function keys positioned in a row that is different from the first set of keys. In another example, the key arrangement includes consonants in the first set of keys and vowels in a second set of keys, with the first set of keys including a two by three array of keys and the second set of keys being positioned in a row other than the rows of the two by three array of keys. The keys may be toggle keys. The characters may be input via multi-tapping the keys, word completion, and/or other known text entry techniques.
