Just so you know, the extension shortcut is (probably) going to be changed soon. Don't hesitate to let me know your thoughts at https://github.com/reblws/tab-search/issues/2 if you have a github acct. Or reach me by email.
I didn't know the shortcut conflicted with a macOS shortcut! If that's a default key-combo that makes me feel even more strongly about changing it.
