Abstract

A communication terminal having a display; a keypad having a plurality of keys associated with several letters each; processor means controlling the display means in accordance with the operation of the keypad. The communication terminal has a predictive editor program for generating an output containing words matching a received string of ambiguous key strokes. Furthermore the communication terminal has on editor application controlled by the processor means for editing a text based on the predictive editor programs interpretation of key strokes. The editor application comprises means for storing string of entered words, means for storing a sequence of key stokes, said sequence is updated upon the occurrence of a new key stroke, and being used as input to the predictive editor program, means for storing a list of matching words received from said predictive editor program. The processor means combines the text string and one word from the list of matching words for displaying in the display of at least a part of said text string and one word from the list of matching words, said one word from the list of matching words is marked in comparison to the remaining part of the text string and added to the text string upon acknowledgement by the user. The terminal comprises means for acknowledging a word suggested by said predictive editor program, and said acknowledging means includes a key on the keypad indicating that a word suggested by said predictive editor program is a part of a compound word, said editor application fixes the suggested word as an acknowledged part of the compound word, resets said sequence of key strokes serving as input for said predictive editor program in order to determine another part of the compound word independently of the acknowlegded part of the compound word.

Claims

1. A communication terminal having:

a display;

a keypad having a plurality of keys associated with several letters each;

processor means controlling the display means in accordance with the operation of the keypad;

a selectable predictive editor program for generating an output containing words matching a received string of ambiguous key strokes;

an editor application controlled by the processor means for editing a text based on the predictive editor programs interpretation of key strokes, and comprising;

means for storing string of entered words,

means for storing a sequence of key stokes, said sequence is updated upon the occurrence of a new key stroke, and being used as input to the predictive editor program,

means for storing a list of matching words received from said predictive editor program,

said processor means combines the text string and one word from the list of matching words for displaying in the display of at least a part of said text string and one word from the list of matching words, said one word from the list of matching words is marked in comparison to the remaining part of the text string and added to the text string upon acknowledgement by the user; and

means for acknowledging a word suggested by said predictive editor program, and said acknowledging means includes a key on the keypad indicating that a word suggested by said predictive editor program is a part of a compound word, said editor application fixes the suggested word as an acknowledged part of the compound word, resets said sequence of key strokes serving as input for said predictive editor program in order to determine another part of the compound word independently of the acknowlegded part of the compound word.

2. A communication terminal according to claim 1 wherein the processor controls the editor application to add a flag to the position of the partial fixing of the compound word, said flag is used later on if wrapping of the compound word is needed when displaying.
