I've just installed ubuntu 13.10 (never used linux before) and Houdini 13.
I'm trying to make the alt button preform like the space bar for viewport navigation. I have found the check box under the main preferences and checked “Use Alt key for view controls”
I've installed Unity tweak tools and disabled “Invoke HUD” allocated to the alt key.
Under system settings I cant find any keyboard shortcuts assigned to the alt key.
What do I have to do in Unbuntu to stop it from calling the alt button when in Houdini?
Cheers
