On a Linux OS, I'm are unable to bind "special keys" as controls like grave and backslash. As I don't use WASD for my control, it became really difficult for us, non WASD player to play this game on a Linux system. From the past, it wasn't really a problem because, we could use it anyway as a general NONE used key.

Because If you try to bind it ingame, it will not do anything at first, but if you press it a second time you will bind that key to NONE.

But, since 1.7, keys that are bound to NONE cannot be used anymore! and so, the game became unlikely unplayable. And no, I can't play it on Windows or even Wine because, it is the only platform that support well java. On a Windows system, it always crash for me.

so if I were you, dear programmer, (I know what it is to do such a job) I would put this on hight priority. Because, it does not only affect Linux users but, every Unix users. Including Mac Os user I think.
