When I use my old, slow PC at home, I find it easiest to make a handwritten note of which forums I want to visit and then I navigate using the scrolling menu at the screen bottom. This also has the effect that I always read the board from the bottom up.... The 'next newset topic' button is also your friend if you carefully read the menu in each forum. When using a fast computer at work, I heartily second Beckles' suggestion.
