Pages, references, and data items are generally displayed using a ‘View’ page. This is a formatted view of the page, where the plain text file with markup is rendered to an HTML file for readability.

The View source action lets you see the plain text MemoWiki source of a file, without risk of accidentally changing it. The buttons available are the same as for a normal view, so you can click either Edit button if you do want to change the page.
