Hmm. Good question. Not that I know of.

input map, but that seems hacky.

I agree sifting through the L&F seems hacky.

I don’t think I understand exactly what you’re trying to implement here. 
If you give me a more concrete example: maybe I (or someone on this 
list) can offer a more concrete suggestion?

I’ll add some context in case this speaks to your question.

By default Swing gets this information in places like 
BasicTextUI#getInputMap(), which calls:

InputMap shared =
     (InputMap)DefaultLookup.get(editor, this,
     getPropertyPrefix() + ".focusInputMap”);

The following works on my Mac & Windows machine (I think using JDK 19), 
but I wouldn’t be surprised if it fails in other platforms / L&F’s. It 
feels brittle, but it might (?) have potential:

private KeyStroke getCopyKeyStroke() {
InputMap inputMap = (InputMap) UIManager.getDefaults().get("TextField.focusInputMap");
for (KeyStroke keyStroke : inputMap.keys()) {
Object action = inputMap.get(keyStroke);
if ("copy-to-clipboard".equals(action)) {
return keyStroke;
         }
     }
// this will show all the default keystrokes
//                System.out.println(Arrays.asList(inputMap.allKeys()));

return null;
}
