Is it possible to disable roblox's use of WASD keys and the Arrow keys?

I want to be able to change what the A & D keys do, in coordination with a locked camera similar to mouselock, so that A and D dont rotate the character and move left or right; but rather cause the character to "shuffle" left and right (using a different animation obviously). If I'm able to how, where is the game directory to be able to change it? Thanks (Also thanks for anyone answer my "alt key" question)

just do

for i,v in pairs(game.Players:GetChildren()) do
	v.Character.Humanoid.WalkSpeed = 0
end
