keyboards and mobile

[BySteve]

this is most like just a me issue but i play on mobile and i saw where we able to use keyboards on here which i thought was pretty cool doing instead of holding a fairly large device and doing the awkward thumb stretch, i got a bluetooth keyboard with my device that i decided to use but i realized that you cant change key binds i wanted to just know if that intentional or a bug cause id definitely enjoy playing with WASD keys instead of arrows

I've also used the keyboard on my cell phone, I realized that you can't change the shortcut for the walking arrows, WASD would be much better
