I am sure there used to be a way to search for text in the output of a Jupyter notebook cell (I think just ctrl+f used to work). Using ctrl + f now just searches for text in the Jupyter notebook code cells and not the output - Is there a way to search for text in the output as well?
It may not be ideal; however, if you click in the right place first, you can activate the browser’s search. If you click the gray area just at top or side in classic notebook view, and then do command or ctrl+F that should work. For JupyterLab, click the bar just above the notebook first. Once you have the browser search active, you can use command+G to go to the next instance. At least in Chrome.
Clicking the cell first will just search code in that cell.
