That's the solution to working with any laptop: just push the F-n button.
Edit: (let's give the post some substance) You may also be able to modify the inventory by slowly double clicking on the item name, I'm not sure. Also, if you set the count to 0, it may be auto-removed (again, not positive). For future reference, if the CS ever fails you, try MWEdit or the Enchanted Editor, both are good for stuff the usual one can't do.
