We have a new page editor. It's way better than the old one. It's all pretty intuitive, but below is an outline of basic functionality and things you should be aware of.
The old editor ("Legacy") remains. You can choose to continue using that or use the New one.
While pages can be edited in either of the editors, we suggest making a clean switch to the New editor to avoid complications.
To use the new editor, create a new page or edit an old one and click Open the Page Editor (New). This style of page editor will be familiar. All controls are in at the top under dropdown menus and as two rows of icons (you can hover on the icons to view their function).
The default font and size of the editor matches your site's defaults. For branding and consistency, we suggest not changing these.
In the editor, write your header.
Highlight the text and from the options provided select H2.
In the editor, highlight the text you want to turn into a link.
From the options provided select the Link icon.
