You can also run `guix repl` and type the variable name (you might need to import some modules before, I didn't check). Most of the time however, these variables are explained in the manual.
I tried the advise to use `guix repl` and type the variable name, but
it displayed nothing so it apparently needs to import the modules
before.

It is a good advise. Thanks

Thanks for your answer, Julien
