1. A computer-implemented method, comprising: receiving input in a first writing system; presenting the input in the first writing system in a first interface element of an interface as content input, wherein the first interface element is a default interface element for presenting the input and a default entry command of the first interface element copies the input into a target location in the interface; calculating a temporal length of the input, the temporal length representing a duration of actuation of an input device corresponding to the input; comparing the temporal length of the input to a threshold value; when the temporal length of the input is greater than or equal to the threshold value, identifying the input as representative of content input in the first writing system; when the temporal length of the input is less than the threshold value, identifying the input as representative of content input in a second writing system; and when the input is identified as content input in the second writing system: identifying one or more candidates in the second writing system based on the input in the first writing system; and presenting the one or more candidates in the second writing system in a second interface element that is separate from the first interface element, wherein a first candidate in the second writing system is copied into the target location subsequent to a corresponding selection of one of the one or more candidates in the second interface element.
