I need a role to edit pages and create/delete pages only. The Admin role is too power with functions that I don't want the editor has.

Create a new Security Role "Editors"  in Admin :: Security Roles and add all the users, you would allow editing all pages.

For all pages, they shall be able to edit, grant "Edit" permission on page level. They can add and delete modules and create child pages as well. 

I have the Editor role works for editing. But only one thing, no Module for select to add to a page. please help.
