Hi EEDSS
Although I'm totally unsure about what it is you are doing or
trying to do, I'll take a stab in the dark here.
Assuming the arrows are already present and you are simply
looking for a method to bring focus to the topic in question
without clicking it, you could try configuring the topic as the
default topic for your project. Then ensure you auto-synchronize it
to the TOC.
Hint - to auto-synchronize to the TOC, you edit the window
properties. To configure the default topic, you edit the
!SSL!/Microsoft HTML Help layout properties.
Cheers... Rick
