Try the following (this works in the last version of TeXmacs):

1) Select "Tools -> Selections -> Import -> Scheme".

2) Cut (section "Introduction") from another application and
paste it inside TeXmacs.

In order to know how the scheme code looks like, you can export
a file to scheme, or copy and paste it as scheme.

Try the following:

1) Select "Edit -> Preferences -> Security -> Accept all scripts".

2) Type "M-e e" for starting an "extern".

3) Enter "string-append tab Hi tab there",
so that you have <extern|string-append|hi|there>,
and press return.

You should see the evaluation of (string-append "hi" "there"),
which is "hithere", on your screen. The extern commands are
scheme commands; you may use "eval-system" for evaluating
a shell command.
