craig_s_russell: I've mapped 'I' to Inventory, '[' to Previous Inventory Item, ']' to Next Inventory Item and 'E' to Use Inventory Item.

I'm on the first level, I've found the security key. It's the only thing in my inventory, so the security key shows in the HUD as the currently selected item.

But when I try to open a security door by getting as close as possible, looking at the door and pressing E, nothing happens.

I've tried remapping the Use Inventory Item to different keys, but nothing works.

What am I doing wrong here? What's the process to use an inventory item like a key on a door?

Thanks,
Craig
