This additional navigation feature can be interpreted as a shortcut between sibling folders. For folder navigation, the basic navigation rules are applied, noticing the following:

￿￿Moving from one folder to another has no effect on the function of the Back softkey in these views: from all of them the back function leads to the previous hierarchy level.

￿￿The navigation shortcuts can only be applied when there is no other use for the left and right scroll keys in the state.

Navigation using Links

Links leading from one application (or idle) to another application may exist. Links are one-way shortcuts: there is no direct path back to the state where the link was started; instead, the navigation inside the linked application functions as if the user had manually activated the other application and navigated to the target state.

For more information on links, see the Application handling section.

5.UI COMPONENTS Lists and grids

Vertical lists are used extensively in most applications. Two dimensional grids are less frequently used, but have obvious advantages in some situations. In lists and grids, the user can move the focus from one item to another using the navigation keys. This is called browsing or scrolling.

￿￿Vertical browsing is preferred over horizontal browsing in general; the keypad solutions should take this into account.

Highlighting

When a list or grid is in use, one item on it is always in focus. The item in focus is indicated by a graphical means called highlighting; the item is said to be highlighted.

The appearance of highlighting on a list item is a coloured (or gray) bar which completely occupies the item in focus. The item text and graphics are displayed on the bar.

Grid item highlighting is a frame over the item in focus.
