Edit a page shown in a frame
If you're editing a frames page in Page view, you can select the frame you want to edit by clicking it. When you are editing a nested frames page, you can also edit the HTML code, but you must first open that page in a new window.
To open a page for editing in a new window
In Design view, right-click the frame, and then click Open Page in New Window.
To return to the frames page, on the File menu, click Close.
