Enhanced DataTips have a context menu
Because of the transient nature of DataTips inside Visual Studio 2005, you may not be aware that there useful operations you can perform on selected item within a datatip by opening a context menu on it.
In the above example, the cursor has been hovered to the m_strTitle member of pDoc->m_strTitle and the right mouse button was clicked. This invokes the context menu for the item and your presented with a set of operations you can perform on it.
My biggest complaint about this feature? I wish that I had had time to add the "Copy Expression" and "Copy Value" commands to the watch window. :)
