Following a trail of bread crumbs

A bread crumb is a listing of pages — such as TWiki > Sandbox > WebHome — that you can travel through to get to a page. As you jump around inside wikis and wiki webs, remembering where you've been and where you are might become difficult. In this situation, bread crumbs come in handy. Because most wikis make liberal use of links, you click and click, winding your way through all sorts of webs and pages before you land on just the right page. When you do land on that page, you want to know where the heck you are. Usually, there are many ways to know that, such as looking at the local web navigation (in the address bar of your Web browser program), which usually says the name of the web. However, that tells you only the web — not how deep the page you are on is in the web and how to get there. Bread crumbs give you this information.

At the top of Figure 2-2, the line that reads You are here: TWiki > Sandbox Web > WebHome is a bread crumb. In TWiki.org, the first part of the bread crumb is the name of the web you're in. The second part is a list of pages that you could travel through to get to that page.
