1. A method of enabling input on a handheld electronic device, the handheld electronic device including an input apparatus, an output apparatus, and a linguistic source stored on a memory, the input apparatus having a number of input members with at least some of the input members each having a number of linguistic elements assigned thereto, including input members having a non-diacritical version of linguistic elements assigned thereto and at least one diacritical version of those linguistic elements assigned thereto, and other non-diacritical input members having only non-diacritical versions of linguistic elements assigned thereto, the method comprising: detecting an actuation of one of the input members; based upon the detection of the actuation, determining whether to output (i) a non-diacritical version of a linguistic element assigned to the one of the input members or (ii) a diacritical version of the linguistic element assigned to the one of the input members in response to the actuation, the determination comprising: determining whether the actuation corresponds to a first alphanumeric input for the enabled input, based upon a determination that the actuation corresponds to the first alphanumeric input for the enabled input, determining to output the non-diacritical version of the linguistic element assigned to the one of the input members, and based upon a determination that there have been previous alphanumeric inputs for the enabled input, determining whether to output the non-diacritical version or the diacritical version of the linguistic element based on whether the previous alphanumeric inputs satisfy a predetermined condition; and outputting the determined output using the output apparatus.
8. The method according to claim 1 , further comprising outputting another output as an alternative to the determined output selectable by a user.
