Make Autorun or movement possible while in inventory

Lots of games already have this, and this would make pvp and all types of combat a lot easier because you can interact with your inventory while moving around instead of having your character motionless while you have to adjust something in your inventory.

Normal movement like forward, left, right, backward, and jumping, should be possible while you are in your inventory, and the cursor has no effect on direction while in your inventory since you use it to move around items. If this seems too complex then at least an auto run keybind would be useful so you can set yourself to moving forward while looking at your inventory.
