1. A computer-implemented text entry method employing a display and a multi-key keypad, comprising operations of:

  • via the keypad, receiving user entry of a sequence of keypresses in an order, the sequence of keypresses representing an intended series of letters collectively spelling-out some or all of a desired textual object, where resolution of the intended series of letters and the desired textual object is ambiguous because some or all of the keypresses individually represent multiple letters;

    after each new keypress, automatically and substantially concurrently preparing alternative interpretations of the sequence of keypresses according to multiple inconsistent keypress interpretation strategies, comprising;

    employing a one-keypress-per-letter interpretation of keypress sequence to identify each entry in the vocabulary matching the keypress sequence, and each entry in the vocabulary with a stem matching the keypress sequence;

    employing a multi-tap interpretation of keypress sequence to identify each entry in the vocabulary matching the keypress sequence, and each entry in the vocabulary with a stem matching the keypress sequence;

    utilizing the display to provide a human-readable presentation including a selected combination of vocabulary entries identified by one-keypress-per-letter interpretation and vocabulary entries identified by multi-tap interpretation,where the operation of utilizing the display comprises, in response to user submission of the keypresses having occurred within one or more predetermined application contexts, varying a display proportion as between presented entries arising from the multi-tap interpretations and presented entries arising from the single-keypress-per-letter interpretations.
