I found an old post referring to multiple selection of files (http://forum.openkm.com/viewtopic.php?f=8&t=400). If there are still UI challenges to make this workable, how about a slightly different way to achieve one use case that I come across.
If I am batch uploading anywhere from 3-10 similar documents, I likely want similar, if not the same, keywords and categories for all uploaded documents. Instead of entering keywords and selecting categories for each document, it would be good to be able to do it for the first document, then from the right-click menu, select "Copy Categories/Keywords", then for each of the other documents, "Paste Categories/Keywords".
It doesn't give all the functionality of multiple selection (eg, multiple moves within the taxonomy) but might at least solve some usability issues.
