The Rename Class refactoring allows to rename a specified class and automatically corrects all references to the class in the code.
To rename a class, first select it in any of the project views or the code editor and press Shift-F6 (Refactoring | Rename...)
Specify a new name for the class and press the "Find Usages" button. IDEA will search for
usages of the selected class and display a result window.
The "Search in comments and strings" option controls whether the name of the package will
be searched in comments and string as well.
The result window displays all found usages of the class being renamed.
You may exclude any usage you need from being renamed by pressing Delete when the usage is selected.
When pressing Delete on a file or a package node, all usages in this file or package will be excluded.
You may also include previously excluded usages by pressing Insert on a corresponding node.
The usages renamed are:
Press the "Do Rename" button (Alt-D) to rename all specified usages. It will close the preview window upon finishing. If you wish to cancel renaming, press the "Cancel" button (Alt-C).
