The various buttons on the button bar are links, and so are Thumbnails and Bookmarks. Also built in are links within publications and on the welcome screen. Most of these links are textwords or strings of words-such as the titles of publications. You can recognize these words as links because they are a different color.
Colors vary on different monitors.
Another way to tell if words, buttons, or images are links is to move the cursor over the area. If the cursor arrow turns into a pointing finger, then you've found a link.
