Library /sys$common/syshlp/lse$menu.hlb DECW help dialog  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Context-sensitive help is available for all of the items on the
  pull-down and pop-up menus.

  To get help, position the pointer to a menu item and press the HELP
  key.  Help information appears in a window and can remain in view
  while you continue to use LSE.
