+#### Copy blocks
+
+Copying blocks allows you to reuse configured blocks across different pages.
+
+When you execute the "Copy" action on a block, it creates a new entry in the "Clipboard" section of the Page Blocks toolbox. Inserting the block from the clipboard adds an exact replica of the block, including its configuration, as it existed at the time of copying.
+
+The clipboard can store only one block at a time. The content of the clipboard remains accessible while editing pages and is visible only to you.
