It would be nice if you could select several papers and assign a keyword to them. At the moment, it is only possible to select one paper.
Hi, we have implemented your feature request!
When you select multiple references, simply drag them over to the Keyword you would like to add it, wait for the Keyword to blink, and they will all be tagged.
Bulk editing / tagging is going to be essential!
Agreed! Also, I can't see a way of editing or deleting existing keywords in bulk.
