Multiple Key Gestures

Ok, so I'm digging up old threads again, but, based on http://stackoverflow.com/questions/2181991/multi-key-gesture-in-wpf you can do this:

class KeyChordGesture : KeyGesture
    {
        private readonly Key _key;
        private bool _gotFirstGesture;
        private readonly InputGesture _firstGesture;

        public KeyChordGesture(ModifierKeys modifier, Key firstKey, Key secondKey) : base(Key.None)
        {
            _firstGesture = new KeyGesture(firstKey, modifier);
            _key = secondKey;
        }

        public override bool Matches(object obj, InputEventArgs inputEventArgs)
        {
            var keyArgs = inputEventArgs as KeyEventArgs;
            if (keyArgs == null || keyArgs.IsRepeat)
            {
                return false;
            }

            if (_gotFirstGesture)
            {
                _gotFirstGesture = false;

                if (keyArgs.Key == _key)
                {
                    inputEventArgs.Handled = true;
                }

                return keyArgs.Key == _key;
            }
            
            _gotFirstGesture = _firstGesture.Matches(null, inputEventArgs);
            if (_gotFirstGesture)
            {
                inputEventArgs.Handled = true;
            }

            return false;
        }
    }

 Then associate it like this:

Editor.InputBindings.Add(new KeyBinding(EditorCommands.SelectAll, 
    new KeyChordGesture(ModifierKeys.Control, Key.K, Key.X)));

 Hope that helps anyone looking in the future.

Just revisited this post from many years ago because I ran into the same requirement and lo and behold Matt's solution works like a charm.

Thanks Matt!

This is the solution that keeps on givin'.  Exactly what I needed.  Thanks Matt!
