Hi there 

Thanks for posting to Lucidchart Community! You can copy and paste text from Notes by clicking on the note icon on the shape and copying the text inside. If you want to add notes to shapes you can find out more about it from the Attach Images and Notes Help Center article. For information about adding text to shapes please have a look at our Work with Text article as well. I hope that helps! Feel free to let me know if you have any further questions!
