It’s always good before posting a new topic to go to the search box, there all keywords related posts should pop up… it works I’d say 95% depending on what keywords you use. Old posts have a chance at reviving, it happens. 
I’m not sure what jump to link is, do you perhaps mean the list below of the various topics and the most recent active on the top. Therefore use the search box, if that helps. - I think topic is similar if not same.
Also if you want skip the unread messages and go to the last update just use the arrow /blue line on the right to pull down, you can also jump to the beginning with arrow up.
