Wacom Cintiq Pro [1] is a series of display tablets. They support 5 touch keys on the tablet. Those keys represent specific functions. They turn display off; bring up OSD; bring up On Screen Keyboard; bring up desktop control panel; and turn touch on/off. The most left touch key, that turns display on/off, is controlled by firmware. When the display is off, the mode is on. Otherwise, the mode is off. So, it works like a switch. That's why we introduced a new switch: SW_INDIRECT. Other four touch keys are true software keys. We use the existing KEY_BUTTONCONFIG and KEY_CONTROLPANEL for OSD and control panel. But, we have to request two new keys: KEY_ONSCREEN_KEYBOARD and KEY_MUTE_DEVICE since none of the existing keys support those two actions.
