Listen for key combinations, such as Ctrl+C and Ctrl+Win+Right Arrow

[Tsunlong]

Hello,

I need to create some functions to listen for Windows key combinations, such as Ctrl+Win+Right Arrow (Desktop Next).
When I run the following program and press the keys manually, it works fine.
However, when I press the Desktop Next key(a special function key) on the keyboard, it seems only Ctrl is captured and blocked, while Win+Right Arrow is executed.
 

Code:

var timeOutTime = -3;
if (keys.waitForKey(timeOutTime, KKey.Ctrl, up: false, block: true) &&
    keys.waitForKey(timeOutTime, KKey.Win, up: false, block: true) &&
    keys.waitForKey(timeOutTime, KKey.Right, up: false, block: true))
{
    print.it("Pass");
}
else
{
    print.it("Fail");
}

I can't use "
 

Code:

if (keys.waitForHotkey(-3, "Ctrl+Win+Right"))

 "because it results in "Failed to register hotkey. Hot key is already registered (1409)."

Sorry, I’m a beginner. My code is based on examples from the cookbook and responses from ChatGPT.
Is there any other way to achieve this functionality? I would really appreciate it.
Thanks.

                var mod = keys.getMod();
                for (int i = 0; i < a.Length; i++) {
                    if (k.Key == a[i].k && mod == a[i].m) {
                        R = i + 1;
                        return true;
                    }
                }
            }
            return false;
        }, block);
        
        return R;
    }
}

Or maybe you can use a trigger.
