Chapter 2. Performing the Treo Essentials > Navigate the Treo User Interface

Navigate the Treo User Interface

The engineers at Palm went to a great deal of effort to design the Treo user interface so that it's ruthlessly efficient at allowing you to carry out common tasks with minimal effort. Everyday tasks such as making a phone call and replying to an email message were studied in detail, with the end result being a reduction in the number of actions required on your part to carry out these tasks. For example, dialing a recent number on your Treo requires as few as three button presses via the five-way navigator. These efficiency gains in the Treo user interface are subtle, but they dramatically affect the device's usability. The following sections examine the basics of navigating around the Treo user interface and uncover some of these efficiencies.

Traverse Screens and Controls

Although you might have an affinity for using the stylus, eventually you will come to appreciate the usefulness of the five-way navigator. With this control, you can move throughout the Treo user interface with your thumb while holding the device in the same hand. In other words, you can do just about anything on your Treo with one hand. Granted, I wouldn't recommend typing text with one hand unless you have a physical limitation, but most people are accustomed to using a mobile phone with one hand. The five-way navigator enables you to carry this usability pattern over to your Treo.
