+CLOSING THE POPUP WINDOW			*popup-close*
+
+Normally the plugin that created the popup window is also in charge of closing
+it.  If somehow a popup hangs around, you can close all of them with: >
+	call popup_clear()
+Some popups, such as notifications, close after a specified time.  This can be
+set with the "time" property on `popup_create()`.
+Otherwise, a popup can be closed by clicking on the X in the top-right corner
+or by clicking anywhere inside the popup.  This must be enabled with the
+"close" property.  It is set by default for notifications.
