I’m glad you find SelectMenu useful. I’m a little surprised you’re unable to assign keyboard shortcuts to the added items. I can’t test it, since I can’t run versions older than CC 2019 with recent versions of macOS. It does work with newer versions. Do you have the option to create an Action with “Insert Menu Item?” There is a way to use AppleScript to choose any menu item, which you might find help for on scripting forums. — Rick
