How You Can View and Modify Frames
To select an existing frame to edit or view in the Frame Editor, open the Frame Editor from the Develop tab's Components portlet by using any of the following methods:
• Select the frame component and click File, Open or File, View
• Double-click the frame icon
A working copy of the frame is opened in the Frame Editor if the frame is available for editing. If the desired frame is not available for editing (that is, it is checked out by another developer), it will be opened for viewing only.
