Use Return or non-printing keys for menus

[DaWrecka]

I'm trying to configure FNV so my Steam controller's face buttons do the same as they would on an Xbox controller. It's... not entirely possible, but not too bad. Or at least, it wouldn't be too bad, if I could assign Enter as the Accept key in menus. But I can't figure out how to do it. I'm familiar with how to change the buttons used, but I can't figure out how to use Enter/Return.

 

I've been using vats_menu.xml as my testbed. At the top is a fairly clear block of:

    <_PCButton_X>    return_button </_PCButton_X>
    <_PCButton_E>    accept_button </_PCButton_E>
    <_PCButton_R>    special_attack_button </_PCButton_R>
    <_PCButton_F>    special_attack_2_button </_PCButton_F>

I tried changing the _PCButton_E to _PCButton_Return, _PCButton_Enter, _PCButton_ENT and _PCButton_RET, but none of these work; strangely, the E key remains the "accept" button - by which I mean pressing Return won't commit the VATS attack in-game, but pressing the E key does. I'm aware that changing what the game displays has to be done further-down; Right now I'm more concerned with getting Enter to do the job.

 

tl:dr; I want to use Return as my "accept" key in menus. How do I set this in the menu XML?
