If change page title in define pages editor, how..?

[hara]

Hello,

I want to re-mane the built-in page title, such as Page 2, page 3...that can be found in admin tools/define pages editor. Where can I change the title? How many files are related it and also need to be edited for working?

Thanks in advance.

Get the 3rd party addon for about us and read the readme file

There are 8 files/edits to create a new page which is preferable to changing 8 files for a built-in page
