RichTextBox and Menu shortcuts ^M ^X

As soon as I put a RichTextBox on a form, my menu shortcuts (regular dropdown menus) for ^M and ^X stop working.

The RTB is apparently intercepting these.
I've tried various tricks like catching this in RichTextBox1_KeyDown and setting the keycode=0,
setting AutoVerbMenu true/false, Locked true/false, setting form KeyPreview true/false
etc. etc.

The only way I can get these 2 shortcuts to work is to set the RTB.Enabled=False.

Any ideas? Thanks, DaveBo

I've found that:
^M won't work at all
^X won't work if the rtb is locked.
Others may also be intercepted, e.g. for the rtb popup menu.

Workaround1:
Ensure the RTB doesn't have focus.

Workaround2:
Let the RTB capture the keystrokes and redirect them.

Code:

---

Private Sub RichTextBox1_KeyDown(KeyCode As Integer, Shift As Integer)
    If Shift = 2 Then          ' Check for some Ctrl-keys
        Select Case KeyCode
        Case Asc("M"):          ' Trap on ^M
            KeyCode = 0
            mnuFileMake_Click
        Case Asc("X"):          ' Trap on ^X
            KeyCode = 0
            mnuFileExit_Click
        End Select
    End If
End Sub
