I do not want screen shots to automatically open in an email - how do I change that default. Has happened since Ventura 13.1 update.

Change the location in Options.

First press command shift 5 to open Screenshot and display the tools.

Then click Options neat the bottom of the screen.

Then select something other than Mail in the Save To section.

Thank you. Can I specify Desk Top as the default?

Yes. That is the first option in the list.
