So I have my inventory button bound to TAB because I'm used to it there from other games, however I've noticed that once I have my inventory open, once pressed again, the TAB button wont close the inventory and instead takes on a function more similar to when you use TAB on a website or text application and will jump around outlining inventorys and items (I've added a screencap to help illustrate).
I've had a look through settings and can't seem to find a work around, maybe I've missed something but if not would there be a future possibility to edit the default TAB key bind?
