Adobe is asking for your feedback help in building a new reference guide for Photoshop CS6. It is in beta online, but requires only a visit to the web page, nothing to install.
The Quick Reference Guide is being built right now, and your feedback is being sought to make it more useful for you and all users.
You enter search terms, refine the responses, and get results showing what’s new in CS6, Tools to do the task you’re interested in, and Keyboard Shortcuts.
It is in an early stage of development, and so needs your input.
