I'm new to Ubuntu and coding in general, so sorry for this probably basic coding question. I am trying to play Minecraft on my computer and the keyboard buttons won't work. So I google, and found this thread http://ubuntuforums.org/showthread.php?t=1316071. Except, I don't know how to "add" this line of code? to a folder and have no clue what is going on. By any chance, could someone explain? Thanks for the help.
