Copy and paste works like the delete action, which lets you delete a block by dragging the delete action on it.

To copy a block, just drag and drop the "copy" action widget inside the sidebar to the target block. To paste, drag the sidebar "paste" action to an object, and the clipboard content will be pasted just after that object.

You can create custom widgets that can be inserted by drag and drop just like standard blocks.

To do so, activate the "Fetch label" mode as follows.

Click on the blue floating button, at the bottom left, that says Grab labels. If it is a red button that says Stop grabbing labels, this means that the label grabbing functionality is already active.

When you are done with label grabbing, click on the Stop grabbing labels button to return to normal behavior.

Then, from the right sidebar, create a widget by clicking on the appropriate button. Give it a name and paste the label you just copied as a reference for the widget.

Once the widget is created, it appears in the sidebar along with your other widget. Drag and drop widgets to replicate the content any where.

Actually, the clipboard is just a widget that has the "clipboard" name. You can edit it in the widget dashboard and give it another name. This instantly creates a new widget (and the clipboard is emptied).

In the Editor tab of the right sidebar, there is a Select pane. This pane is designed to handle multiple selections. Here is how it works

• Option/Alt click a block to add it to the selection list, do it again to remove it. Alternatively, you can remove an element in the list by Option/Alt clicking on it.
• Elements in the list can be re-ordered by drag and drop.
• Dragging the Paste block to a destination inserts the blocks after the target. To insert it before, hold Option/Alt key when dropping.
• Clicking the Delete block will delete the source blocks.
• Click the Clear List block to empty the list.

Warning: blocks in the select list are identified by their internal ID, which encodes their type and position in the document hierarchy. As a consequence, if you want to paste several times the selection, the Ids may point to different blocks after the paste. To secure the Ids, paste

• outside the original container
• or inside the same container, but after the source.

For the same reason, it is safer, after using the Delete action, to clear the selection list.
