+						*complete-popup*
+When "popup" is in 'completeopt' a popup window is used to display the "info".
+Then the 'completepopup' option specifies the properties of the popup.  The
+option is a comma separated list of values:
+	height		maximum height of the popup
+	width		maximum width of the popup
+	highlight	highlight group of the popup (default is Pmenu)
+Example: >
+	:set completepopup=height:10,width:60,highlight:InfoPopup
 
 The "kind" item uses a single letter to indicate the kind of completion.  This
 may be used to show the completion differently (different color or icon).
