Key Codes is a little utility that displays the key code, unicode value, and modifier keys state for any key combination you press. If you're a developer, this might be useful to you.

What’s New

Version 2.1

Added a popover that breaks modifier flags down into known constants and their values.

Many Tricks Does Great Stuff!!!

I just discovered these folks as a company and they are both good and serious (no junk, but sometimes a little fun tossed in). I am trying their apps now (an option if you go to their website) and their apps are great (so far). Just discovered they are also on the App Store, so I came here to write a review.

They only need to improve the abiltiy to understand all the features of their apps. Every app should have a modest but decent manual, perhaps along with some good brief videos, that explain (not just show) what the apps can do. FAQs are not a substitute for a manual.

Must Have!

This app has saved me so much time across several projects. Would have no problem paying $5+ for this. Great job!

Perfect app to find key codes

Shows you the key codes associated with different keys. Very useful when using Apple Script to simulate key presses.
