LLastClick
ListHandle theList ; handle leading to a ListRec returns last cell clicked (loWord is h, hiWord is v) cell most recently clicked.
theList is a handle leading to a variable-length ListRec structure. It is a value previously obtained via LNew. Returns: either a 32-bit long integer, or a Cell, depending on your programming environment. The low word is the horizontal index and
the high word is the vertical index of the most recently clicked cell.
Notes: LLastClick returns the same value as that stored in the lastClick field of Note that this does NOT necessarily identify the last cell selected or a cell
in which a double-click occurred. It is simply the last cell in which a
mouseDown occurred. However, if called directly after a call to LClick that returns TRUE, it does return the cell that was double clicked.
