Closed Crafting screen opens and closes when using volume switch

Although this may sound great its actually rather annoying when ever I turn volume down on my laptop it seems to trigger the crafting menu.

This is whilst using a physical button on the side of my laptop.

 

Pretty sure it isn't a bug, but i can't confirm it as i don't know what the devs intended. But different function keys do different things in the game. When i press F7 which is my mute button, it moves the character right. When i press F8 which is my lower volume button, it brings up my crafting menu too, so i'm guessing either You are pressing a function key or something that acts similarly to one.

 

Already confirmed as a bug, the devs are aware of it. See:
Lenovo T530 volume down opens crafting

 

Alrighty, so it is a bug, and some reason pressing these keys acts as pressing multiple letter keys but without the unicode attached to it. But this has all already been mentioned so i s'pose this thread is done.
