Listening To Hotkeys

Including hotkey-listening logic at runtime

To listen to key presses, use the HotkeyPressed event:

// Add a HotkeyPressed event.
hkl.HotkeyPressed += Hkl_HotkeyPressed;

private void Hkl_HotkeyPressed(object sender, HotkeyEventArgs e)
{
    if (e.Hotkey == hotkey1)
        MessageBox.Show($"First hotkey '{hotkey1}' was pressed.");
    
    if (e.Hotkey == hotkey2)
        MessageBox.Show($"Second hotkey '{hotkey2}'was pressed.");
}

Unlike with the standard KeyDown and KeyUp events, here only the registered hotkeys will be detected.

If you'd like to get the details of the active application where a hotkey was pressed, use the SourceApplication argument property:

private void Hkl_HotkeyPressed(object sender, HotkeyEventArgs e)
{
    if (e.Hotkey == hotkey1)
    {
    	MessageBox.Show(
            "Application:" + e.SourceApplication.Name + "\n" +
            "Title: " + e.SourceApplication.Title + "\n" +
            "ID: " + e.SourceApplication.ID + "\n" +
            "Handle: " + e.SourceApplication.Handle + "\n" +
            "Path: " + e.SourceApplication.Path + "\n"
        );
    }
}

As a special feature (still in Beta though), if you'd like to get any text that may have been selected when a hotkey added was pressed, use Hotkey Listener's GetSelection() method:

private void Hkl_HotkeyPressed(object sender, HotkeyEventArgs e)
{
    if (e.Hotkey == hotkey2)
    {
        // Get the selected text, if any.
        string selection = hkl.GetSelection();
    	
        // If some text was selected, display a MessageBox.
        if (selection != string.Empty)
            MessageBox.Show(selection);
    }
}
