The source editor lets you edit the full HTML source of any page. You can use the source editor to add content regions or make any other changes that you can't make in the visual editor.
The editor features syntax highlighting, bracket matching, and multiple cursors. It will also highlight
special classes such as
cms-editable for convenience. This source editor is only accessible
to administrators, not clients.
To access the source editor, open a page for editing and select Edit Source from the sidebar.
To save your changes, select Save Changes from the sidebar.
Changes made in the source editor will not be saved as a revision and will not be shown in activity.
