Hi witcher,
If you look at the text box propeprties, you will see "Previous Text Box" and "Next Text box". If your text box are indeed linked, these properties will have a reference to another text box. You can use this to navigatethrough all the text boxes of a chain
Something like:
set TB to object reference of current box
repeat
if previous text box of TB is not null then
set TB to previous text box
else
exit repeat
end if
end repeat
set aTextBox to TB
repeat while aTextBox is not null
set aTextBox to my ProcessBox(aTextBox)
end repeat
on ProcessBox(ThisBox)
tell ThisBox
-- do stuff
return next text box
end tell
end ProcessBox
Warning: This is untested code !!!
