• The default for the label size has been increased from 0.08 to 0.12
  
  
• You may specify any of the four location parameters kx_lo, kx_hi, ky_lo, ky_hi. Previously if we wanted to set the location, all four parameters had to be set.
  
  
• The command PPL LIST SHAKEY returns the location of the shade key even for a default shade key. Note that the shade key is located relative to the corner of the plot, not the axis origin.
  
  
• Can change the location of the labels from right to left and top to bottom, by sending a negative value for the label size. By default the labels are on the right if the key is vertical and below the key if it is horizontal.
  
  
• The labels are right-justified for vertical shade keys that are labelled on the left (though they may not look it, depending on the font)

  Example: shade key located across the bottom of the plot, with its
  labels above it.
