A translcuded page can be converted to a normal page with the content mirror on that page by "forking" the page. Since trancluded pages are the default for the OER Remixer, this is a useful activity for editors of the library. Let's consider the first chapter's exercise set in the OpenStax Calculus text.
If the transcluded page is tagged properly, there will a "forker" icon next to its name as shown below.
If you press that icon (and it may not exist), a window should pop up that lets you ":fork" the page (copy the source content from the source pages into the translcuded page). This effectively removes the trancluded nature of the page and make it a customizable/editable page.
If that icon is not on the title, the forker can be accessed via the the "Options" pull-down menu on the black bar. This will open up the same popup window with the same effect.
As with all edits, the effects of forking can be undone by going to the "Revision History" option under the same "Options" pull-down menu and reverting to the previous version of the page.
