In Linux version of the game, my controller doesn't work and I cannot confirm the player with a keyboard, I can press left and right and swap between characters, but I cannot confirm. Pressing 1 does nothing and pressing ESC closes and instantly re-opens the same menu. Basically, I cannot play the game.

Why not explain that in game directly? I don't think there's any reason to use Tekken notation instead of an actual binded key (or a controller button) on that particular screen. Plus, even if the player is familiar with the notation, he still needs to know which keyboard keys are being used by default.
