Description
Use the selectedChunk function to determine which text is selected.

Value:
The selectedChunk function returns a chunk expression of the form
   char startChar to endChar of field fieldNumber

Comments:
The return value reports the selected text: the startChar is the first 
character of the selection, and the endChar is the last character.

If no text is selected but the text insertion point is in a field, the 
startChar is the character after the insertion point, and the endChar 
is the character before the insertion point. In this case, the endChar 
is one less than the startChar.

If there is no insertion point or text selection, the selectedChunk 
function returns empty.

To get actual text that is selected, use the selectedText function.
Try

on tabKey
	put the selectedChunk into foo
	answer foo
end tabKey
