A hand-held communication device provides navigation key-based predictive
text entry. The hand-held communication device includes a housing
generally sized to be held in a human hand having a display disposed for
displaying characters selectable for entry in a character position of a
text string being entered and a navigation key assembly for scrolling
through and selecting from the characters displayed by the display. The
characters displayed by the display during text entry are arranged
according to the probability of selection of each character for entry in
the character position so that the character with the highest probability
of selection is selected with a single input from the navigation key
assembly.
