    Trying to be minimal in order to reduce constant editing 
    of layer keys, not to mention how ugly having a 60% layout 
    is when you have mapped keys in the grid.

        Put simply, the below line allows for toggling a no-bind
        layer for when you may require a standard layout (such as
        playing Street Fighter, Counter Strike, etc.) by pressing
        both Alt/Option keys at the same time. You can toggle back to the
        base layer by holding both Alt/Option keys at the same time, as to 
        allow for normal functionality when holding either key down for a shortcut.
