21. In a computing device requiring input of information, a method for assisting a user with completing input, the method comprising: displaying a user interface comprising a sequence of input controls that are arranged sequentially for receiving user input, said user input including user-supplied information for input into said computing device; marking all input controls as initially unfilled, for indicating that each of the controls has not yet received input from the user; and assisting the user with completing input for the input controls, by: (1) receiving navigational input for moving a screen cursor among the sequence of input controls; (2) if the navigational input specifies forward movement, positioning the screen cursor at a next one of the sequence of input controls that is unfilled; (3) if the navigational input specifies backward movement, positioning the screen cursor at a previous one of the sequence of input controls that is unfilled; (4) receiving input from the user for the input control that the screen cursor is currently positioned at; (5) upon completion of input by the user at the control, marking the control as filled, for indicating that the control has received input; and (6) repeating substeps (1)-(5) until the user has completed all input desired.
