I haven't actually tried this but something like the following may work with
a little bit of effort.

1) Shift-click at the end of the text to place the cursor either at the
   end of the text or to select all of the text from here to the end of the
   text.
2) Use one of the new functions of HC 1.2 that allow you to find what
   has been selected (ie. selectedChunk).  If you are at the end of the text
   (ie. it is all visible) the selection should be empty.  If not, it will
   be something like char 25 to 28 of bg fld "temp"

Hope it helps,
