Add normal support for MacOSX Keychain and form auto-fill

Please, add normal support for MacOSX Keychain and form auto-fill.
This is one of the functions (or 2 functions) preventing even temporary switch to Roccat.
The good implementation is Safari 6.1 multiple-logins Keychain support, where pressing Down button in the Login field brings you the list of saved users and selecting one autofills the password for you,
— and Firefox (Opera etc) behavior when pressing Down button on a textfield shows you the list of ≈10 previously sent strings, refining while you type.

Thank you!

Roccat 4 now has form auto-fill, we currently don't have a password option as it's important  that we take our time to engineer a very secure implementation.
