If you start jboss-admin with the --gui option, it will bring up a GUI instead of a command line. Note that --gui also implies the --connect option because the gui doesn't work in a disconnected state. You should use the --controller option if you need to use a host and port other than localhost:9999.
jboss-as-7.1.0.Final/bin> ./jboss-cli.sh --gui
You will see a screen that looks like this where you can browse the domain model:

If you double-click on a previous command, it will be selected and copied to the command line. You don't need to copy and paste by hand.

The command is also copied to the system clipboard so you can paste into your favorite editor. This is handy for creating scripts.
