Abstract: Methods, systems, and apparatus, including computer program products, in which an input method editor receives input in a first writing system and presents input candidates in the first writing system or a second writing system. In one implementation, a method is provided. The method includes 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; automatically identifying one or more candidates in a 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.
