	By default, neither cursor is selected. A selected cursor is displayed in a different colour on screen and the index of the selected cursor can be retrieved programmatically. Only one of the graph's cursors can be selected at any one time. If the user clicks on a cursor, that cursor is selected. If the user clicks on the graph itself, the selected cursor is deselected.		By default, neither cursor is selected. A selected cursor is displayed in a different colour on screen and the index of the selected cursor can be retrieved programmatically. Only one of the graph's cursors can be selected at any one time. If the user clicks on a cursor, that cursor is selected. If the user clicks on the graph itself, the selected cursor is deselected.

	Note that you can select and deselect a cursor using the <code>CURSORPOS</code> command.		Note that you can select and deselect a cursor using the <code>Programmer_Guide/Shell_Items/Graph/SET_GRAPH#CURSORPOS\|CURSORPOS]]</code> command.

	A message is sent to the graph when a cursor is selected or deselected.		A [[Programmer_Guide/Shell_Items/Graph/GRAPH_Messages#CURSORSELECTED\|CURSORSELECTED]] or [[Programmer_Guide/Shell_Items/Graph/GRAPH_Messages#CURSORDESELECTED\|CURSORDESELECTED]] message is sent to the graph when a cursor is selected or deselected.
