No, Tim, you idiot.  You should have tried it before making this
suggestion.  First, there's a display bug.  If you find successfully
and then "select the findChunk", then the text appears selected, but as
soon as the user does anything, the findChunk goes away, leading to the
text becoming unselected in appearance, even though it is still the
selection.  Selecting a range and finding it have different
rectangles.  Try and see what I mean -- finding a phrase in a title
field gives a rectangle which stops at the last letter of the title;
selecting the findChunk at this point selects all the way to the end of
the line on which the last word appears; so after the findChunk
vanishes, you're left with a spurious black rectangle starting right
after the last letter and going to the end of the line.

Second, the find command does *not* start after the current selection.
It starts at the end of the findChunk or at the beginning of the
current card (if there is no findChunk).  So this technique leads to
display anomalies and to finding the same string over and over again.
What a pain.

It looks like we're stuck with counting the "find index" of each string
in the card, then repeating the search that many times plus one on
"find next".  This is so nasty a hack that I believe it qualifies as a
bug in HyperCard.  There should be some global property specifying a
chunk expression for the next search to start at.  There isn't one in
HC 1.2.1; does anyone know if this has been added in a later version?
