Chrome Key Event Tester

Test press, release and character events for JavaScript and PPAPI.

A simple app to help with debugging keyboard issues with Javascript and PNaCl. How to use: The left-hand-side shows a summary of the keyup, keydown and keypress JavaScript events, including which keys were held down simultaneously; the right-hand-side shows the equivalent PNaCl events. Hover over a key bubble for more details, or click "Debug log" to view a copy/pastable version for submitting bug reports.
