5. A computer-implemented method, comprising: detecting a current input to an interface; calculating a temporal length of the current input, the temporal length representing a duration of actuation of an input device corresponding to the current input; comparing the temporal length of the current input to a threshold value; identifying the current input as content input in a first writing system if the temporal length is greater than or equal to the threshold value, or as representative of content input in a second writing system if the temporal length is less than the threshold value; copying the current input into a target location in the interface, if the current input is identified as content input in the first writing system; and identifying one or more candidates in the second writing system based on the current input in the first writing system, for display in the interface, if the current input is identified as representative of content input in the second writing system.
