Let Players use Arrow and WASD keys to move/boat (PC).

A while ago my "D" key fell off my laptop, making me unable to use that key to type, play games and more.
I found a solution by copying the letter (capitalized and not capitalized) into my clipboard.
However, it is still pretty hard to do normal things with my computer.
I have to resort to not clicking the key on my computer to move. Ever play Minecraft without a crucial key? A little hard.
I have to alternate between typing the capital and not capital version of that letter, which gets really frustrating sometimes.

I noticed, if I'm in a boat in Minecraft, I can't use the arrow keys to turn and I have to hold "A" to spin the boat around to the point I want.

I'm sure there are some people like me, and since my arrow keys aren't broken it would be great if we could use them.
