40611 ripley 13 
  A pairlist of the names of open graphics devices is stored in
14 
  \code{.Devices}. The name of the active device (see
15 
  \code{\link{dev.cur}}) is stored in \code{.Device}.  Both are symbols
56382 murdoch 16 
  and so appear in the base namespace.

  \code{.Device} is a length-one character vector.

  \code{.Devices} is a \link{pairlist} of length-one character vectors.
22 
  The first entry is always \code{"null device"}, and there are as many
23 
  entries as the maximal number of graphics devices which have been
24 
  simultaneously active.  If a device has been removed, its entry will be
25 
  \code{""} until the device number is reused.
