Mapping joystick diagonals to letter keys?

[Morte tha Talking Skull]

So im playing this super cool game called “Subterrian: Mines of Titian” and its a grid based traditional roguelike rpg similar to Tales of Maj’Eyal, Caves of Qud, or Cataclysm Dark Days Ahead. And the issue im running into is that the game does not use a standard WASD control scheme, and instead, uses WASD for cardinal directions, and also uses QEZC for diagonal movements instead if hold both W and A at the same time since its a turn-based-grid-based game.

Does anyone know of a way on the steam deck input mapper where I can map sat the upper left diagonal direction to Q, upper right to E, lower left to Z and lower right to C? There is only 4 slots for mapping options but i gotta assume theres some kind of way to do this that im just not seeing.

Thanks for the help! When I’m done with my layout i will make it available for the community if anyone cares for it!

Unfortunately there is no 8 way binding option for dpad, but you can do a 9 button touch menu.

You can make it invisible. You can make input continuous or when you click. If you want continuous movement when you click, you can do that too by adding an action layer with a touch menu set to continuous. Then add a click command to hold the layer. On the default set, you can set the trackpad to single button with a click to hold the layer with the touch menu on it.

I've done something like this using dial menus on stick and touchpad.
can work with any amount of direction keys, you just need to figure out how they align and then make them auto-fire.
after figuring out how they worked i made the dials invisible.
if you do it on touchpad you can also make it act on "press touchpad"
