In-page Variable block editing
The page editing window also allows you to edit variable blocks and variables that appear on the page. These are only editable if the editor has the appropriate Permissions.
The two topics shown on the right of this page - Variable Editor and Variable Block Editor - take you to the relevant help topics..
Note that editing Variables and Variable Blocks through the interface may alter the content on more than the single page being edited, as Variables and Variable Blocks can appear in multiple locations on your site.
