On this page, I simply used the chain link button above in the top row of buttons.
I type the text: Link to Anchor
I selected the text I just type, and pressed the chain link button.
In the search for post/page area, I selected the page “Test Anchor”
BUT before I clicked on “Add Link”, I clicked the cursor at the end of the link: http://staffordmotorspeedway.com/test-anchor/
after the last slash, I typed: #testanchor – simply the same name I typed for my anchor on the last page. THEN I click “add link.
