CoLT (short for "Copy Link Text") is a tiny extension for Firefox which makes it easier than ever to copy a hyperlink's associated text. CoLT includes a means of copying both a link's text and URL at the same time. This feature is particularly handy for bloggers, web developers, or anyone else who finds themselves writing links to other places on the web. The latest release allows users to create an unlimited number of custom formats for copying both the link text and location.
