How to activate revision info in line number view

Question

I know of an Eclipse feature to show revision information (gradual coloring, more info like revisionnumber, date and author on mouseover) for the last changes in a line in the linenumbers-view.

Does anyone know how to activate this feature for a file, or even better, by default? I accidently hit some shortcut lately which made it show in one file, it does not show up in the others, though.

This is called "Show Annotation" and you can find it in the "Team" menu. Since this is a pretty expensive operation, you can't make it the default.
