I think the clipboard only holds one item at a time. If you copy something to the clipboard it only saves the last thing you copied. I use Notepad and save links in a text file and give it a name (like Links.txt) and save it to my desktop or another convenient place I can remember 😊 Then all you have to do is open the text file with your saved links and copy whichever one you want then paste it into your browser's URL address at the top if it's a link and you can open the page.

Normally when you copy anything it goes to the clipboard and when you paste it somewhere it comes from the clipboard.
