Quick find a field or method in Eclipse's workspace

ctrl+o (cmd+o) opens the quick outline where you can search for a method within the current class. Pressing ctrl+o again extends the search scope to the complete class hierarchy.

The closest thing I know of is the Java Search, which allows you to specify searching for a method, field, class, etc. If you're in the Java or Java Browsing perspective, Ctrl+H will open the Search dialog with Java Search as the selected type.

If you want to request a feature or enhancement, enter it into Eclipse's Bugzilla. Keep in mind that the backlog of feature requests is HUGE, so the most effective way to get yours noticed is to take initiative and submit a patch.

With the ctrl+h you will have some more options to search.

Under java search option you may find search for type, method, package, constuctor, field.

Also you may find "Limit To" option to narrow your search result and get precise search result!
