This sounds more like Visual Studio than Eclipse. The other editors in eclipse don't do this.

Yes, they do. Or at least the Java editor does.
BTW this was reported by a user.

I can't find this in the Java editor, running Eclipse 3.6 on linux and Mac. Is it hidden somewhere?

It works for me on Windows without any special settings/configuration.
The actions are "Shilft left" and "Shift right" Maybe they aren't bound to keys by default on Mac?
