In some situations, while edit text on page, or in the WYSIWYG pane, you may want to delete hidden tags and markers, e.g. styles, tags, Bell etc.
To delete hidden tags and markers, navigate with arrow keys close to the point where you believe there is a hidden tag or marker, and then press CTRL+Backspace to remove them.
Note
This functionality is based on the DelTags system scripts and it overrides the tags protection as explained in Protecting tags against deleting.
