    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 keys at the same time. You can toggle back to the
        base layer by holding both alts at the same time, as to allow
        for normal functionality when holding either key down for a shortcut.
