What will be an ideal response?
The user interface is composed of visual controls that are metaphors. Therefore, the UI designer must rely on what the user already knows or is reasonably expected to know. Consistency in the user interface is achieved when the user can predict what kinds of actions produce what kinds of results. Consistency and predictability of expectations are essential both to the vocabulary and the syntax of the user interface. Users cannot learn everything from scratch every time they work with a new application.
