Creating a Bookmark Within a File

The Workbench allows you to create bookmarks in files that you edit so that you can quickly reopen those files from the Bookmarks view ( Window > Show View > Other... > General > Bookmarks).

With the file open in an editor, right-click in the gray border at the left of the editor area, next to the line of code or text that you want to bookmark.
Select Add Bookmark from the pop-up menu.
Notice that an icon for the bookmark now appears in the left border of the editor area. A line is also added to the Bookmarks view.)

You can reopen the file for editing at any time by double-clicking the bookmark in the Bookmarks view.
