Indesign drag duplicate does not work with this latest version

still an issue for me too, running tahoe 26.6.2, have installed multiple versions of indesign

I’m so annoyed. The drag and copy isn’t working for me. I’m on a Mac, I just unintalled, reinstalled, and the double black and white arrow appears but it only copies the item I clicked not everything selected. I have several image frames I want to drag and copy, but only one of the image frames actually copies. 

Just a note that the feature works as it always did on Windows. 

For reference, it would be helpful to know your OS version in case others have this issue.

OMG Thank you this has been driving me crazy.

This does not work for me. Never turns to two white arrow. I'm on a mac platform 😞

Hmmm. I had some whackiness happening with various option/command/shift click combinations. A restart seems to have put things back to normal. Pretty bizzare behavior for a mature software program. 

It did not work for me....

If Katie's suggestion to reset preferences does not work you might want to try uninstalling and reinstalling InDesign in the following manner:

In the app section of your Creative Cloud desktop app click on the “V” next to the app’s (InDesign) name and choose the “Uninstall” option from the pull-down menu that appears. After you’ve run the uninstall then use the Creative Cloud Cleaner Tool Use the Creative Cloud Cleaner Tool to solve installation problems . Then reinstall the program through the Desktop app. Before you reinstall, once again trash all preference files to make sure that your install is completely clean. Then launch InDesign and see if the problem persists.

Please be rest assured, however, that the dragging of duplicates works exactly the same as it always has. If Katies's and my suggestions don't work for you then please let us know what operating system that you are using. Also please make sure that the version you have of InDesign Cc 2019 is the latest release 14.0.1.

Shift constrains it and Options duplicates it. If you are doing everything correct then try resetting your preferences. Set preferences in Adobe InDesign

1. Exit the application
2. Press and hold Shift+Ctrl+Alt (Windows) or Shift+Option+Command+Control (macOS) as you start InDesign. You are prompted to delete the current settings. The new preferences files are created when you start the application.

But it may be as simple as when you are holding the option key. In InDesign the option needs to be held prior to clicking or dragging or through the release of the mouse. The option key works in many applications to duplicate as you drag but when you hold the option key alters depending on the application.

Adobe Photoshop: You need to hold the option key prior to clicking and dragging the object.

Adobe Illustrator: You need to hold the option key through the release of the mouse.

Adobe Premiere: same as Illustrator but you can not hold it early as it will only select one part of the clip.

Adobe InDesign: The option key can be held prior to clicking on the object OR on the release of the mouse.

If you hold the option key too late and release it too early then it will not duplicate. I always hold it prior to selecting the object AND through the release of my mouse except in Premiere Pro. That way I do not have to think about it and it always works.
