title: Shortcuts Ctrl+C Ctrl+V dont work in Textboxes if MenuStrip has this Shortcuts set
body: <p>Goal: A Menustrip with Copy and Paste and the user shall see the Shortcut-Keys.</p>

  <p>Problem: If you have a MenuStrip and set the ShortcutKeys the are "catched" by the Menu but no longer by the Textboxes. This means you cannot use Ctrl+C / V in the Textboxes - only by Right-Click. If you remove the Shortcuts the Textboxes work fine.</p>
  
  <p>Why is that? Whats the solution if I dont want to name the Entry "Copy______Ctrl+C"?</p>
