Thanks! I don’t have a particularly deep motivation here, other than curiosity. If you’re wondering how my curiosity got piqued initially, it was something like this: A while ago, someone at work was adding copy/paste support to some component that didn’t have it. I noticed that they “hardcoded” the shortcut “ctrl C”. And I thought to myself: Swing already “knows” that this is the right keyboard shortcut, in the sense that all components that support copy/paste “out of the box” use it. It would be nice if there was some way to ASK it to tell me what it “knows”.

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; } Regards, - Jeremy ------ Original Message ------ From mark.yagnatin...@barclays.com<mailto:mark.yagnatin...@barclays.com> To micklen...@gmail.com<mailto:micklen...@gmail.com>; client-libs-dev@openjdk.org<mailto:client-libs-dev@openjdk.org> Date 3/3/24, 6:00:46 PM Subject RE: how to get find out the keyboard shortcut for the paste action? Thanks for the response! I didn’t expect to get one at this point ☺ It does indeed answer my question! (Though you didn’t quite get the name right: there’s no Ex at the end… I take it you’ve done some Windows programming at some point) But now I have a new question… Is there any way to get the “usual” letter for a “common” operation? For instance, lots of programs support copy and paste. Is there a way to ask Java “what is the standard letter for paste” and get back “V”? Again, one could create a scratch text area and grovel through its input map, but that seems hacky. This message is for information purposes only.
