12. An apparatus comprising an input device having a plurality of selectable input items enabling text input by ambiguous input sequences entered by a device user, the apparatus further comprising a processor and a display, wherein the processor is arranged to control a primary process of receiving a user input on the input device, wherein an input sequence is being generated in dependence of selection of an input item by manipulating the user input device, wherein each input item is associated with at least one character, the generated input sequence corresponds to the sequence of input items that have been selected, and wherein the generated input sequence has a textual interpretation of the characters associated with the input sequence, wherein the textual interpretation is ambiguous, and displaying on the display a textual interpretation; and wherein the processor is arranged to control a secondary process, initiated upon receiving an input associated with a delete-character command, of: deleting a character of the textual interpretation, at a position thereof, wherein the deleted character corresponds to a first input item, and returning to the primary process where textual interpretations associated with the deleted character for said position are excluded, and displaying an updated textual interpretation, wherein the updated textual interpretation, at a position corresponding to the deleted character of the textual interpretation, has another character being associated with a second input item of the input device, wherein the second input item is in vicinity of the first input item; such that the primary and secondary processes are performed until a user input associated with a confirm-text command is received.

The apparatus of claim 12 , further comprising a timer arranged to determine a time after reception of the input associated with a delete-character command during which no further user input associated with characters is received and to provide a time value to the processor, such that the exclusion of the interpretations associated with the deleted character is timed out after a predetermined time if no further user input associated with characters is received during the predetermined time after reception of the input associated with a delete-character command.
