Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing scanning options in user interfaces to facilitate the selection of input options in the provided user interface. In some implementations, a method may include displaying a first user interface including a first set of at least three scanning options. Also, the method may include receiving a selection of a first scanning option of the first set, and displaying a second user interface including a second set of scanning options based on the selection of the first scanning option. Further, the method may include receiving a selection of a first scanning option of the second set, and determining that the first scanning option of the second set defines a single input option that does not result in additional input options, and in response performing a command associated with the single input option.
