Upgrade Storagebibtex export
It looks to me as if the bibtex export feature will use underscores ( _ ) in constructing the key (at least it did the first time I tried it). The problem is that in latex an underscore is used in math mode to indicate a subscript; the upshot is that latex will halt with an error if you try to use one of those cite keys in your document. Could you please substitute, say, a hyphen for an underscore (or at least make this user-selectable)?
