Abstract: A system displays a filtered list of elements in response to receiving user input of a desired string associated with a list of elements. The system includes a user interface control, such as an edit control, for receiving the input, and determines whether elements matching the desired string exist in the list of elements. The system provides the ability to search internal strings of an element and various levels of a hierarchical list. If no matching elements exist, the system displays the entire list and provides an option to add a new element to the list.

Abstract: A method for processing user-input that may include a command to abort a previously requested operation and typed-ahead data entered in anticipation of completion of the previously requested operation is disclosed. The user-input is represented by a value queued in a first queue by an operating system. According to the present invention, the value is removed from the first queue and examined to determine if it represents a command to abort the previously requested operation. If the value represents a command to abort the previously requested operation, the previously requested operation is aborted. If the value does not represent a command to abort the previously requested operation, the value is queued in a second queue, and, after completion of the previously requested operation, the value is removed from the second queue and associated with a display window to which user-input is focused at that time.
