||When you want to press onscreen buttons or select items onscreen such as application and settings icons, simply tap them with your finger.
|Press and hold
||To open the available options for an item (for example, a contact or link in a web page), simply press and hold the item.
|Swipe or slide
||To swipe or slide means to quickly drag your finger vertically or horizontally across the screen.
||Press and hold your finger with some pressure before you start to drag. While dragging, do not release your finger until you have reached the target position.
||Flicking the screen is similar to swiping, except that you need to swipe your finger in light, quicker strokes. This finger gesture is always in a vertical direction, such as when flicking the contacts or message list.
||For some screens, you can automatically change the screen orientation from landscape to portrait by turning HTC ChaCha sideways.
||In some apps, like Gallery or the web browser, you can “pinch” the screen using two fingers (for example, thumb and index finger) to zoom in or zoom out when viewing a picture or a web page.
