Abstract: A method for browsing in a visual content such as a document or a list. The content is available on a terminal having a browsing command. Part of the content is displayed on a display of the terminal. The browsing commands enable the contents displayed on the screen to be made to scroll in the direction specified by the command introduced. The displayed part is duplicated into two identical images when one end of the content situated in the direction of movement specified by the browsing command is displayed on the means for displaying. A first image remains still and a second image moves in the direction of movement specified by the browsing command so long as the command is active. In this way, the user sees that the command has indeed been taken into account and notes visually that the end of the visual content has been reached.
