Google Docs: still no working clipboard

I've been using Google Docs for ages, and there's been no progress in providing any kind of reasonable clipboard functionality with any OS X browser. We're told to use ctrl-c to work with the system clipboard instead of using the native Google Docs clipboard. Of course that shortcut works for Firefox on OS X, but not Safari.

Honestly, Google Apps is still a semi-useful toy compared to a desktop application. Progress is very slow.
