The documentation isn't overly specific on this:

https://help.ubuntu.com/community/slrn

only saying that it can be done.

command-line

  1. Best Answer

    Based on the source code, it looks like the editor is chosen as

    1. an (uncommented) assignment of the form set editor_command "..." in the user's .slrnrc file

    2. any of the following environment variables, in order:

       SLRN_EDITOR
 SLANG_EDITOR
 EDITOR
 VISUAL

    3. an OS-specific default, which in the case of a Unix type OS is vi

    So if you are observing that it is choosing nano rather than vi in the absence of an explicit ~/.slrnrc assignment, it is likely due to one of the mentioned environment variables.
