Sorry for the confusion with this.
In Balsamiq Mockups 3 for desktop, here are all the ways to clone a mockup:
- from the project menu
- from the mockup dropdown menu in the navigator
- by right clicking a mockup in the navigator
- by using the keyboard shortcut (“CTRL+SHIFT+N” on Windows or “CMD+SHIFT+N” on Mac)
Also, here is the complete list of shortcuts you can use in our little tool if needed: https://docs.balsamiq.com/desktop/shortcuts/
Please let me know if this works for you or if you need any further support, we’re here to help!
