CKEditor is mainly configured on a per-text format basis, but there are some global settings. This video shows how to configure those global settings.

• Go to “Configuration => Content authoring => CKEditor” (admin/config/content/ckeditor)

Here, you’ll see that there are two default profiles. The “Advanced” profile is enabled for the “Filtered HTML” text format, and the “Full” profile is enabled for the “Full HTML” text format. We can also edit the global settings. Let’s go ahead and do that before we jump into the profile settings.
