Align Center keyboard shortcut (Shift+Command+C) hijacked!

[Scott Citron]

This has happened before. When working with type in InDesign 19.3, I'm no longer able to invoke Align Center by pressing the default keys (macOS 14.4.1) Shift+Command+C . All other align text commands work as expected, but not Align Center. This problem appeared previously a few years ago, but I have no idea how I solved it. 

(PS: Of course I checked Edit > Keyboard Shortcuts, but no problem here. I also checked the Finder Keyboard settings panel and again came up dry.)

Yes, Scott, this can happen. 

To confirm that it's another application or extension which is grabbing your shortcut, reboot your computer. Open InDesign before any other application (if necessary use the diable application which autoload . Your shortcut wil probably now load.

Then load apps one by one to see which is the culprit. Some utilities or extensions can do this.

It's sometimes quicker to just close all apps and hit the affected key combination to see what happens. If a utility or helper app has captured that key, it will pop up.

(I use Simple Sticky Notes, which by default uses several Alt+[letter] keys and is aggressive about trapping them even inside other apps. It was the work of a few minutes to disable some of those shortcuts and reassign others.)

Success! Restarted my Mac in Safe Mode, which disabled all login items. KBSC problem was gone. After lengthy process of elimination I discovered that Copy 'Em, my trusty Clipboard manager, had a shortcut assigned of Shift+Command+C. Once I disabled that shortcut, my InDesign problem disappeared. Thanks to Steve and James for your efforts.
