Exactly what I needed!

I have a Kinesis Advantage ergonomic keyboard, and I was trying to remap some keys. This app was EXACTLY what I needed so I could see what codes were being sent! It worked flawlessly with El Capitan. Thank you!

Handy little app for developers

Works nicely on Yosemite. And it’s free! Good app to have if you are a Mac developer and looking to figure out keyCodes, modifierFlags and such for keyDown: methods on your views.
