Finding Strings to Externalize

To find strings to externalize:

In a Java view (e.g. Package Explorer), select a set of packages, source folders or projects.
From the menu bar, select Source > Externalize Strings...
A dialog comes up with a list of all compilation units that have some non-externalized strings
In the dialog, you can double click on a listed compilation unit or press the Externalize button to open the Externalize Strings wizard
