The present invention provides a unique system and method that facilitates navigating smoothly and gracefully through any type of content viewable on portable devices. Such navigation can be performed while preserving perspective and context with respect to a larger amount of content. The navigation can be key-based such that one or more keys of a keypad can be employed to browse through, zoom in, and/or zoom out of content. In one aspect, the content can be segmented into any number of sub-sectors or segments such that each segment can correspond to a particular number key, whereby particular portions of content can be viewed in greater or less detail by pressing or tapping on the corresponding number key. Furthermore, when viewing a first portion of content, nearby content can be glanced at by pressing and holding the respective key. When the key is released, the view returns to the first portion.
