How to use "Copy Paths of Selected items..."

After running a search (for instance, “.pdf smith”), Listary produces multiple results. How do I save a copy of the search results? If I click the three dot menu, I see the option “Copy Paths of Selected Items to Clipboard”. But how do you select multiple items in the listary results? Shift+Click and Ctrl+click don’t work. Thanks for any help you can offer.

To my knowledge there is no multiple select.
Thats one of the reasons to use Everything search
