Digital television allows access to the Internet. However, arrow keys on a remote control are not suited for navigating web pages containing non-uniformly spaced selectable hypertext links. A web-browser or operating system window manager may be modified to allow movement of a focus along a co-ordinate system defined by the arrow keys on the remote control and to permit the focus to be positioned in-between the links. Thus, movement of the focus from one link to another is intuitive and predictable.
