HButton can be used to assign more applications to one HW button. If you press the button, the first application is run. If you hold button till device vibrate, second app is run. If you hold button till second vibrate, third app. And so on, and so forth.




Usage:
* Install attached cab.
* Run HBSetup (Programs - HButton - HBSetup), setup up to 5 applications to Button1
* Start Setting – personal – Buttons and assign HButton1 to any HW button.

Now you can run all selected applications using this one HW button.
