Zebra tc 75x


we have a zebra tc 75x where we have modified the scan button.

Now, it's possible to scan with the left button and the right button.

The volume button has replace by the scan button.


But, now it's not possible to make a screen shot with the volume button and the power button !


How i can do for to place the screen shot in other place ?

Could you give me the way ? i've try to bind another button but i can't find the option screen shot ..
