Welcome to our community, ndldn
It won't be possible to highlight. But to coax it to the top
of the page, you need to place the cursor at the bottom of the page
(Ctrl+End does this nicely) and press Enter lots of times to add
"White Space" at the bottom of the topic.
Note that if your user decides to print said topic, the
additional white space will likely cause an extra sheet or maybe
two of paper to be "printed". Not really much of an easy way around
that. It will also possibly cause an unwanted gap if you create
printed docs. But for those, you might apply a conditional build
tag to the white space so that it's removed when you generate
printed docs.
