The Rename Method Parameter refactoring allows to rename a specified method parameter and automatically corrects all references to the parameter in the code.
To rename a method parameter, first position the caret in editor on it and press Shift-F6 (Refactoring | Rename...)
Specify a new name for the parameter and press the "Find Usages" button. IDEA will search for
usages of the selected method parameter and display a result window.
The "Search in comments and strings" option controls whether the name of the parameter will
be searched in comments and string as well.
The result window displays all found usages of the method parameter 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)
