Hi there,

Thank you for getting in touch. That does sound odd. Could you give some basic troubleshooting steps a try as outlined in this article: https://help.figma.com/hc/en-us/articles/360040523973-Technical-troubleshooting-tips#Basic_Troubleshooting?

Often, simply quitting and reopening the app can fix the issue. If that doesn’t do the trick, restarting your computer might help.

Should the problem continue, don’t hesitate to contact our support team: https://help.figma.com/hc/en-us/requests/new. Please make sure you use the email associated with your Figma account, include links to the file in question, and share access with support-share@figma.com. Don’t worry, inviting us to view your file won’t impact your billing.

Thanks,

Toku

UPDATE: after restartng my computer, now it’s working 🤷

I came to report the same thing. I tested right alt with other apps and it works there. Right-alt-drag doesn’t duplicate items anymore, where as left-alt-drag does.

After restarting the app, no change.
