Rename Dialog for a Parameter
Use this dialog to rename a parameter.
In addition to renaming the parameter itself, IntelliJ IDEA can also look for the usages of the parameter name. If found, the changes you are making to the parameter 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 (that is, the places where the name occurrences are looked for) is always limited to the current entity (file, class, etc) and the entities that the current one depends on.
