It would be advantageous to be able to copy from the COMMERCE list those items a particular station is in need of so that it can be cross-referenced when on another station. If this function exists I have not seen it; if so, please advise where it is.

Thanks.

Temporary workaround: /dump
That will take a screenshot, saving it in your vendetta folder (~/.vendetta, for Linux users).

Haven't tried it, but the Desired plug-in may sort of do what you want:

Being able to copy text in general would be pretty handy but, as for the items a station needs and will pay generously for... to my knowledge, that has never been accurate.
