In D8 possibly in D7 you can use 'the selection' to get the selected text 
in a field as opposed to using selStart/selEnd.

property pSelText

on mouseUp
   pSelText =  the selection
   put pSelText -- OR JUST
   put the selection
end mouseUp

That will return the currently selected text in the currently active FIELD.

You can get the same type of thing with a TEXT member by doing this
-- From the lingo dictionary

-- attached to the text member
property spriteNum
on mouseUp me
     mySelectionObject = sprite(spriteNum).member.selectedText
     put mySelectionObject.text
     put mySelectionObject.font
     put mySelectionObject.fontSize
     put mySelectionObject.fontStyle

end

Either of these methods gives you the currently selected text to do with 
what you will. ;)
Hope that helps.

Later.
