dom.getSelection()

Availability	3.0
Description	Gets the selection, expressed as byte offsets into the document's HTML source.
Arguments	bAllowMultiple
	The argument is a Boolean value indicating whether the function should return multiple offsets if more than one table cell, image map hotspot, or layer is selected. If this argument is omitted, it defaults to FALSE.
Returns	For simple selections, an array containing two integers. The first integer is the byte offset of the beginning of the selection. The second integer is the byte offset of the end of the selection. If the two numbers are the same, then the current selection is an insertion point.
	For complex selections (multiple table cells, multiple layers, or multiple image map hotspots), an array containing 2n integers, where n is the number of selected items. The first integer in each pair is the byte offset of the beginning of the selection (including the opening TD, DIV, SPAN, LAYER, ILAYER, or MAP tag); the second integer in each pair is the byte offset of the end of the selection (including the closing TD, DIV, SPAN, LAYER, ILAYER, or MAP tag). If multiple table rows are selected, the offsets of each cell in each row are returned. The selection never includes the TR tags.
Enabler	None.
