Dual shortcuts

Hello. I have a requirement for a menu item to invoke a special function with the Shift key. In other words, when F12 (which is the primary shortcut) is hit it does function A and when Shift+F12 is hit it does a variation of function A. An idea is to create a second menu item and set its Shortcut to Shift+F12, but I don't really want to expose that menu, it is an undocumented-type of feature. Any ideas?

There may be another way, but you could always create two similar menu items with different event handlers, and just before the menu is shown you could do something like this:

if( (Control.ModifierKeys & Keys.Shift) == Keys.Shift )
  // remove standard item, and add the special item
else
 //remove special item, and add the default item

Thanks for your reply. Actually it seems I don't really need to do that. I can create a second menu with Shortcut=ShiftF12 and set programmatically Visible=False and it does what I want. It is hidden but the shortcut still gets processed.
