You can go to the form used to edit the Table of Contents using the "Update" button on the Help Manual view. Or, click the "Admin" button on the main command line and then the "Toc" button on the sub-command line below it (see the picture below).

The plus icons and minus icons work as before to expand or contract sub-sections. The sub-keyword icon becomes a sub-section icon and works the same way, to add a sub-section under a section. Note that there are no trash can icons next to sections with a sub-section below it -- you would have to delete all sub-sections first.

The edit pencil brings up an edit form, as in the example below for "Add/Edit Metadata". Note that it asks for a new section name, and also allows you to change the section number. This allows you to move (sub)sections around in the Help Manual -- unlike keywords, the sections need not be alphabetical.

Different users may want different help for the same form field or help icon. Click on Help Types, the next slide along the top, to see how manage help types.
