Description:
Whenever I want to use my shield which is in my offhand and I have my gamer axe in my main hand, it always activates/deactivates the gamer axe. That's inconvenient because I have to right click again to get my gamer axe out. I suggest we use alt + right click to activate the gamer axe when an item is present in the offhand. This is a solution that isn't over complicated and it uses a modifier to tidy things up a little.

You could leave the shielding whenever you disable or enable the gamer axe as that is a minor detail, but it might get a bit annoying if you have blocks in your offhand.

Reason:
Shielding is really useful in combat, and disabling my gamer axe whenever I want to shield it is inconvenient and require a lot of getting used to.
