Sometimes you need to know not only what lines have changed, but also who changed specific lines in a file. This view displays the author and the revision that changed every line in a file. Just click on a line in the editor panel where the file is opened to see the revision that edited that line last time highlighted in the History view and to see all the lines changed by that revision highlighted in the editor panel. Also the entries of the Annotations view corresponding to that revision are highlighted. So the Annotations view, the History view and the editor panel are synchronized. Clicking on a line in one of them highlights the corresponding lines in the other two.
