This is a know bug of LWJGL, see: https://github.com/LWJGL/lwjgl/issues/13

It has been reported with Mac OS with DVORAK keyboard layout and I am fighting with the same problem on a Linux machine using Neo2 ( http://en.wikipedia.org/wiki/Neo_%28keyboard_layout%29#Neo )

Although it is a bug of a library I guess it's Mojangs turn now:

• How can you replace the version of LWJGL Minecraft uses? Since I.7.x it isn't that easy anymore. I did some tries but minecraft simply didn't start anymore.

• Please use the new LWJGL version in the next release

• Another, not that nice but probably much easier workaround: Please allow selecting another key than <SHIFT> in the "Controls..." settings tab as the inventory modifier

Thanks for any kind of help!
