C# Cannot handle Ctrl+K event of textbox

I would like to perform some actions when the user presses Ctrl + K on a textbox.

 private void subject_TextBox_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Control && e.KeyCode == Keys.K)
                  MessageBox.Show("!");
        }

Nothing happens when I run it.

When I debug I can see that e.Control is true (this means I pressed Ctrl) but the e.KeyCode is not equivalent to K.

enter image description here

Any ideas?

 protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == (Keys.Control | Keys.K) && focusedTextbox == subject_TextBox)
        {
           //Some Code
        }
    }
private TextBox focusedTextbox = null;


 private void subject_TextBox_KeyDown(object sender, KeyEventArgs e)
        {
            MethodName(e.KeyCode)
        } 
 private void MethodName(Keys keys)
    {
        focusedTextbox = (TextBox)sender;
    }

Use this code, this should work i have tested it myself and it will work, you will want to run the 'MethodName' method in each textbox, or if you can find a better way to change the 'focusedTextBox' field then do that hope this helped.

Really don't know what is the problem reason.
May the event is fired as soon as the Ctrl is pressed, without waiting to the K to be pressed as well.

However, when I use the same code in the TextBox_KeyUp event, it works fine.

In the KeyDown event, you just ask for the 'state' of the keyboard.
