Command + Click not opening links in new tabs

As @apennebaker commented. The issue ended up being a bluetooth keyboard in a backpack.

Ah, "the old" backpack and keyboard problem.

Obviously not everything is better with bluetooth.

Please check your bluetooth and make sure that is not the cause of your problems when troubleshooting keyboard issues.

While many people might have another keyboard hooked up to their computer, that wasn't the case for me. You can be sure by disabling bluetooth (if your main keyboard is wired).

Other problems I've researched include: specific websites mess with CMD+Click via javascript either intentionally or accidentally. To debug, try a few different websites. If it's just one website that you really want CMD+Click to work on, there are some chrome extensions you can try, I haven't used any of them.

Make sure your CMD key works correctly. The OP in this thread did this via using CMD+0 or CMD+1 to navigate to different tabs.

Not sure what my issue was, but restarting the OS fixed it. Give that a try. Good luck.
