You can try this:

NDiagramCommand cmd = commandBarsManager.Commander.Commands.GetCommandFromId((int)DiagramCommand.SaveDrawing);
cmd.Shortcut = null;
commandBarsManager.Recreate();

This removes the Shortcut from the SaveDrawing command and rebuilds the UI of the command bars manager.

Is there a way to disable the Nevron "ctrl+s" save feature? When the user clicks on the diagram then presses ctrl+s, the nevron save dialogue is displayed, overriding ours. We need to disable this. Is this possible?
