| Tap |
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. |
| Drag |
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. |
| Flick |
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. |
| Rotate |
For some screens, you can automatically change the screen orientation from landscape to portrait by turning HTC ChaCha sideways. |
| Pinch |
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. |
