You can Backup / Save Content from any Editor by saving its HTML code.
This is useful for moving Configure Layout content, Backing up Free-Form pages, etc.

To do this:
Click the "HTML" (Edit HTML Source) Icon in the Editor toolbar second row.
A Pop-up window will appear that says "HTML Source Editor".
Copy All (Ctrl-A, Ctrl-C) HTML text from that Pop-up window.
Paste (Ctrl-V) the HTML text into a NotePad text file.
Save the NotePad file to your Computer.

Now you have everything shown in the Editor saved and it can be restored to another editor at any point by pasting it into another HTML Source Editor window and saving it.
