REFACTORING Window

The REFACTORING window, located in the Cross Function Area at the lower screen border, lists all references of the object (variable, FB Instance, etc.) used in your project for which the 'Refactoring' command was called. Using the window, you can perform an automatic solution-wide replacement of object properties.

You can hide/show the window by clicking the button shown left on the Cross Function Area toolbar.
For closing the window, you can also click the cross icon on the right of the window title bar:
