For example, here is the lynx "Grex Activitives" menu:
GREX ACTIVITIES
There are many things you can do on Grex. Here is a list of things you
can try out.
* Electronic Computer conferencing using "PicoSpan". Grex was first
established primarily for this purpose.
* Converse with other users on Grex, or converse with a helper.
* Electronic Mail or "email" is available so you can send or receive
private messages to Grex users, or anywhere on the Internet.
* Information about Grex
* If you don't know what Netiquette is, you'd better find out!
* Access to Usenet, a world-wide public message exchanging system.
* Internet Services such as telnet, FTP, gopher, and the World Wide
Web are also available, but membership is required.
* There is a collection of On-line games, including NetHack.
* Utilities are available to perform a myriad of small useful jobs.
* Access to a Unix shell, with all standard commands, including full
access to the C compiler, assembler, and other development tools.
* You can also run a single Unix command from here.
* Want to reward someone on Grex? Try sending them mathom.

You navigate in lynx by using the up- and down-arrows to
select the link you want to follow, and then using the right-arrow
key to follow it.
You can use your web browser to tour the lynx shell menus, but be forewarned--since you aren't logged into Grex, many of the commands will not work. Create an account and log on to really be able to use stuff.
