The attached patch adds two movement commands,
`tabulated-list-next-column' and `tabulated-list-previous-column', by
default bound to "f" and "b" in `tabulated-list-mode'. They move to the
next/previous column respectively, and honour a numeric prefix argument.

I'd be happy to try to get my employer to sign the papers, please send
me the forms (in German, if that is relevant).

If possible, feel free to use this patch without papers signed.

Thanks and greetings,

Peter
