You can create a link to another HTML document by dragging and dropping the file icon or by choosing Tools > Link.
Note: If you set up your work area as described in About Publishing, the filename or pathname that you enter in this field does not start with /; for more information, see About URL Translations.
If text, the selected item turns blue and is underlined, indicating it has an attached link. If an image, the item is outlined in blue (unless the border has been set to 0). If you hadn't selected anything, Cosmo Create inserts the filename you are linking to at the cursor location.
