6. The method of claim 5 , further comprising determining that a focus of the processor apparatus is on a location abutting the text entry session, and detecting a selection of an input key at the location as the post-termination linguistic input member actuation.
5. A method of enabling input on a handheld electronic device that comprises an output apparatus, an input apparatus comprising a plurality of input keys, and a memory having stored therein a plurality of language objects, at least some of the keys having characters assigned thereto, the method comprising: detecting selection of a number of input keys in a first key input sequence; responsive to detecting a first selection of one of the input keys, initiating a text entry session on the handheld electronic device, wherein the text entry session comprises disambiguating the first key input sequence upon each actuation of the number of key inputs; detecting an input from the input apparatus as a delimiter input and, responsive thereto, terminating the text entry session, wherein terminating the text entry session comprises terminating the disambiguation of the first key input sequence; detecting a post-termination key input indicating an entry of a linguistic character and, responsive thereto, appending the post-termination key input to the first key input sequence without an intervening delimiter to form a second key input sequence, the second key input sequence concatenating the first key input sequence and the post-termination key input; and responsive to detecting the post-terminating key input indicating the entry of the linguistic character, resuming the text entry session, wherein resuming the text entry session comprises disambiguating the second key input sequence that includes both the first key input sequence and the post-termination key input.
