My slightly odd preference is...

    bash-5.2$ cat .nanorc
    set zero

Together with

    UXTerm.vt100.translations: #override \n\
        Ctrl Shift <Key>N: scroll-back(1, halfpage) \n\
        Ctrl Shift <Key>T: scroll-forw(1, halfpage) \n\
        Ctrl Shift <Key>C: copy-selection(CLIPBOARD) \n\
        Ctrl Shift <Key>V: insert-selection(CLIPBOARD) \n\
        Ctrl Shift <Key>H: set-altscreen(toggle)
