Enable Swipe Up [webOS 3.0]
This tip is only for devices running webOS 3.0 and higher
Although there is no gesture area on the Touchpad, HP kept the ability to swipe up from the bottom of the screen in order to minimize your app into card mode or launch the app launcher. If you have tried to swipe up but nothing happens, you may need to enable it first. To enable (or disable) just open up the "Screen & Lock" app, find the "Advanced Gestures" section, make sure that "Enable Gestures" is set to ON.
The swipe up can be done when the Touchpad is rotated in any screen direction, and will always be done from the "bottom" of the screen. However, note that for some PDK or older mojo apps, the "bottom" of the app may not be the same as the bottom of the screen rotation. This occurs because the app was built for a webOS phone that always had the same screen bottom and does not recognize the rotation of the device, or if you have set a rotation lock. When in doubt, you can always press the Home Button to minimize the app, too.
