You can configure Windows CE to meet the user input requirements of a variety of different platforms. Currently, the keyboard and the stylus are the usual input method on Windows CE-based devices.
Keyboard functionality in Windows CE is similar to that of Windows-based desktop platforms. And, like those platforms, Windows CE supports hot keys. A hot key gives the user high-priority system access for specific purposes, such as canceling a time-consuming file transfer operation.
A unique feature of Windows CE is that it supports the use of a stylus and a touch screen in place of a mouse. Touching the screen with the stylus mimics the left-button mouse click.
