Forgive me for not knowing the two menu buttons on the Xbox Controller. I've been using a USB keyboard in tandem with the controller so I no longer need to hold the select button to bring up a text input field. When I go into the options I see that I can remap what the button does for a quick press-and-release but not for a press-and-hold.
It would be really nice to allow that change in the options. Personally, if I had that text input field switched for something like the map toggle, that would really improve my experience because I often have a hard time seeing the radar, thank you!
