The top frame contains an image map. If you place your mouse cursor over a square, the title of the page will appear. The current page is always indicated by a yellow square.

Each of the squares on the same horizontal line are part of a sequence. Navigate along a sequence by clicking the forward or back navigational arrow icons in the left frame. If a navigational arrow points down, it will lead to a child page or sequence. If one points up, it will lead to the parent page or sequence. The text links in the frame to the left generally refer to pages in the same tour sequence.

I have separated articles, tips, and tutorials into three categories -- General Interest, Macros (how-to) and Templates (how-to). Each area uses a different color so that you can easily find pages or tour sequences by category. The main tour sequence, which includes this page, is the unshaded sequence on the left. The home page is clearly labeled.
