How can I erase a signature from quicklook?

Quicklook allows to insert signatures in documents, and it creates a signatures list. I need to erase a signature from that list.

How can I do that?

See if this is it. Open the Preview.app ( maybe you need to open an image or file.)

From here you can Preview>View>Mark Up Tool

when you open the signatures and hover your mouse, the X will show itself to delete

You may or may not have to quit the application and/or restart to see the Quicklook results(?)

That was it! Thanks!

Great, glad it solved your problem cajimenezs.
