Unfortunately, there is no ‘Anchor‘ support in the SharePoint 2007 wiki wysiwyg editor. If you want to continue using the ‘out of the box’ wysiwyg editor, you’ll need to add anchors in the source view.
To access the html source view, open the desired wiki page into edit mode.
Look for an icon on the editor toolbar that looks like a page with angle bracket symbols.
Once in the source view – look for the location where you would like to add an anchor. If you are not familiar with html this may be a little overwhelming (and I would suggest hitting the w3schools website for some basic html tutorials).
In this example, I am adding an anchor to the bottom of the wiki page called ‘bottom’.
Click ‘ok’ to return to the wysiwyg editor.
We now need the url to the wiki page you are editing –
right click the wiki page in your breadcrumb and choose ‘Copy Shortcut’. Your breadcrumb may look different or be in a different location depending on your master page configuration.
