A browsing session having an improved selection-to-display time is provided based on a tree which relates wirelessly-retrievable items. Responsive to a user-initiated selection that an item be a current item to browse, the item is displayed, a child and a sibling of the item are wirelessly retrieved while the item is displayed, and the child and the sibling are stored in a local cache. Two controls are provided to select from two wirelessly-retrieved items in the local cache that have not yet been user-selected in the browsing session. While the item is the current item, a user-initiated selection of one of the two controls is received to select a new current item to browse. If a first control has been selected, the sibling is retrieved from the local cache and displayed. If a second control has been selected, the child is retrieved from the local cache and displayed.
