How to generate citationkey using shortjournal rather than fjournal?

For an article in the Journal of Scientific Computing, I would like to keep the full name of the journal in the reference, but use the citation key based on JSC rather than JoSC. It can be convenient because sometimes I need to switch between the full and short journal names, while I would like to keep the citation key unchanged.
