Since #822 pressing the windows key gets inserted as ^@, including when using global hotkeys like Win + Left. A Ignore key binding may be needed.

I just installed the 1.0.486 build from AppVeyor and noticed this as well.

I'll fix this soon, but I have a big related change in the works so don't bother with any PRs on this one.
