e.g., many of the external links given in wikipedia articles have a text title rather than a URL address for the hot links.

Those external links in wikipedia also have a cute little icon that let's you know that they'll whisk you offsite. It's to the right of the hyperlink, superscripted, and is basically a little square box with an arrow pointing to the upper right-hand corner.

Ceci n'est pas un seing.
