Many of the comments that T.A. Toolbar produces contain hyperlinks to web resources that describe common errors in more detail.  Some even have small tutorials. To follow these links, students need only control-click the link. This should automatically launch their web browsers and take them to the appropriate site.  If you don't like the web pages that are used in the default configuration of T.A. Toolbar, you can customize them, sending your students to web pages of your own choosing.

Note: Other links in comments are found in the "subsequent" comments. (Please see "Why Button Pairs.")
