Where do i map lt and rt on xbox 360 controller

[PurpHere]

i only find rt and lt on axes but i do not know how to bind them to buttons (button to axis does not work)

I had to use SharpDX_XInput as INPUT and Core_ViGEm as OUTPUT and use Axes to Axes. It was the only way so I could press both triggers at the same time and work correctly.
