, the buttons are highlighted correctly. but when I use the WASD keys, the event processing does not occur. I did not find a solution in the GODOT documentation either. Can someone tell me?
If you look at the input map in the project settings, there’s a switch you can throw to let you see the default bindings, and I believe you can edit them; you could potentially add w to ui_up and so forth, just bear in mind that will potentially interfere with controls that expect text input like LineEdit.
You could also use grab_focus() to take control of button focus yourself…
Personally, the only ui action I ever change is ui_accept where I add the controller’s lower action button. While you can change these th documentation recommends not doing that. and as @hexgrid points out
