Questions about specific refactoring activities

In the sequal you will find eleven different refactoring activities. For each the questions are equally formulated as follows.

(before) How did you perform the refactoring activities before the IDE provided the corresponding functionality?
o I did it manually or used a special refactoring tool.
o I didn't do it or tried to avoid it because the activity was too complicated to perform manually.
o Not applicable, since the IDE's functionality has always been present to me.

(after) How do you perform the refactoring activity since the IDE provides the corresponding functionality?
o I use the IDE's refactoring functionality.
o I don't use the IDE's refactoring functionality although I know it's there.
o I didn't know this functionality of my IDE, therefore I can't answer this question.
