Did you try to capture them in Treeview 's Keypress event?

>I have a top level form and menu in it. Some of menu items have associated key labels. If I press such keystroke it always automatically executes a command associated with menu item. If there are no menu item with such keystroke and it is not processed by active object it produces default sound like as I do something wrong.

>But I have Copy, Paste and other menu items which actually work with treeview elements and I don't want them to execute associated commands if I press Ctrl+X in a textbox for example. Even if I remove KEY clause from menu bar definitions it still produces default sound despite that keystrokes are processed by event handler.
