If you need to add a link into your page copy there are two approaches to this depending on the destination of the page you are linking to, internal links and external links.
Internal links
If you are linking to a page that is hosted on Sitecore (shu.ac.uk) then you will need to use an internal link.
- Locate the text component in the content tree containing the copy
- Open the text editor
- Highlight/select the text that will become the link
- From the toolbar above, select 'Insert Sitecore link'
