Rename dialog for a directory
Use this dialog to rename a class.
In addition to renaming the class itself, PyCharm can also look for the usages of the class name. If found, the changes you are making to the class name can also be applied to these usages.
The usages are assigned to different categories which correspond to the options which you can turn on and off.
Note that regardless of the options selected, the search scope (places where you search for the name occurrences) is always limited to the current entity (for example, a file, or a class) and the entities that the current one depends on.
