How to launch the task manager and kill a running android application with STF ?

[prutapptic]

Hello guys,

I'm investigating STF and I'm facing a limitation:
On the real device, i've a "system" button that display all the currently running application. On this "task manager" view, I can kill some process. On the control screen of STF, there are 3 buttons: "Menu", "Home" and "Back". On my real device, there are 3 buttons: "System", "Home" and "Back".

How to simulate a click on this "System" button ?
How to replace the "Menu" button by a "System" button ?
Does exist a way to display the "task manager" view with STF ?
What is the Shell command to kill an Android process ?

Thanks for your answers.
