  For Future Reference: Context-Sensitive Help
  Context-Sensitive Help is available in the `Help` pull-down menu of the VPE window. Selecting this item creates a cursor in the shape of a question mark, which can then be placed on a tool icon or other feature in the window. Releasing the mouse button invokes the appropriate Help window.
