Thanks for such simple workflow!
It makes simply duplication of current clipboard, and can be corrected with using {clipboard:1}
you can edit workflow, change Copy to Clipboard element to
{clipboard:1}
{query}
Sometimes really hard to find Clipboard history element because matching keyword searching in any position.
I need a way to search from the text line start of an item (first letters).
Trigger of such search like "^" would be fine, or maybe a new Workflow trigger.
