It's really hard for me to tell from the video what this does exactly. I can infer the premise but it's unclear how this works. I've used other keyboard locking tools in the past that were free. What I'd really love is a smarter app that detects keyboard mashing or whatever so I don't have to manually lock/unlock when my cats come around.
