Signature Preview | In this area, the current method signature is shown. (The information in this area is synchronized with the changes you are making to the method signature.) |
In the area where parameters are specified, you can add new ones, edit, reorder or delete the existing ones. The refactoring will distribute your changes accordingly.
To start editing a parameter, click it. Alternatively, use the Up and Down arrow keys to navigate to the parameter of interest and Enter to start modifying it.
