Bonjour Mark,
Sorry if I was not clear enough.
As I said, the selectedChunk, that returns a chunk expression
describing the location of the text selection or insertion point, is
always something like char 4 to 3 of field 1 (insertion point is
placed after char 3 but there is no text selection), char 4 to 4 of
field 1 (char 4 is selected), char 1 to 4 of field 1 (char 1 to 4 is
selected).
word 1 of the selectedChunk = 'char'
word 2 of the selectedChunk = <integer>
word 3 of the selectedChunk = 'to'
word 4 of the selectedChunk = <integer>
etc.
These integers are those that interest us :-)
'char 4 to 3 of field 1' -> '2 < 4' ->' word 2 < word 4' -> insertion
point but no selected text
'char 1 to 4 of field 1' -> '1 < 4' ->' word 2 > word 4' -> selected
text
Why word 4 is less than word 2?
A simple convention to distinguish when the insertion point is in the
field if there is some selected text also or not.
When word 4 is less than word 2, this means that the insertion point
is in the field after char 'word 4 of the selectedText' but there is
no selected text.
If word 4 is more than word 2, this means that char 'word 2 of the
selectedText' to 'word 4 of the selectedText' are currently selected.
See selectedChunk, selectedField, selectedText in the docs.

But I'm not sure what this part of your script does, what it is
checking
for?
if word 4 of the selectedChunk < word 2 of the selectedChunk then
Why word 4 and why word 2?
And why word 4 is less than word 2?
Best regards from Paris,
Eric Chatonet.
