How to click Windows key in Java

Question

Can I click "Windows" key in Java? I need to emulate pressing Win + ARROW_UP keys. May be this button has Key Unicode and it could be called by .getKeyFromUnicode() method? Will be appreciated for any help. Thank you.

1) You can simply try this:

private void pressKey() {

    try {
        Robot r = new Robot();
        r.keyPress(KeyEvent.VK_WINDOWS)
        r.keyPress(KeyEvent.VK_UP); //Windows button is still pressed at this moment
        r.keyRelease(KeyEvent.VK_UP);
        r.keyRelease(KeyEvent.VK_WINDOWS);          
    } catch (Exception e) {
        e.printStackTrace();
    }
}

2) Another variant for solving your task - is sikuli.docs

If you want to simulate pressing and holding one button, while then typing another, use type(TheKeyDoingTheAction, KeyModifier.TheKeyYoureHoldingDown It's written like this:

 type(Key.UP, KeyModifier.WIN)

Please check docs and samples here: http://doc.sikuli.org/keys.html

3) Finally, you could use the following code:

Runtime.getRuntime().exec("rundll32 user32.dll,LockWorkStation");

Note: This will work for Win OS only.
