  SET SELECTION GRAB FOCUS

  Enables grabbing the DECwindows primary selection only when you give EVE
  input focus.

  Usage notes:

  o  This command if valid only with the DECwindows interface, not on
     DECterm or character-cell terminals.

  o  The primary selection is the selection that can be shared among
     DECwindows applications without having to use the clipboard. In EVE,
     you create a primary selection by using SELECT or BOX SELECT, or by
     dragging or clicking M1. (A found range is never the primary
     selection).

  o  When you create a primary selection in another application, EVE loses
     the primary selection. EVE saves the current selection and removes the
     highlighting from the selected text.

  o  If SET SELECTION GRAB FOCUS is in effect, then when you give EVE the
     input focus, EVE grabs the primary selection and restores the
     selection, if any, that was active when it lost the primary selection.

  o  The alternate behavior is to grab the primary selection only when you
     select text. See help on SET SELECTION GRAB SELECTION.
