User interface to enable users to scroll through a large list of items

摘要

Techniques pertaining to efficient scrolling are disclosed. One of the features of the efficient scrolling is the enablement of a search right at an appropriate item in a large list of items, thus avoiding going through the long list and wandering back and forth around a desired item. According to one embodiment, an indexing display is used. The indexing display includes a list of indexes, each corresponding to a group of items that sharing one or more common characteristics (e.g., a character or a kind). The indexing display is allowed first to be scrolled for a desired index. Once the desired index is confirmed, searching for a desired item in the large list starts at an item indexed by the desired index.
