[NTG-context] Figure captions: "Fig." instead "Figure"

Hello, what is the way to change caption text for figures to be "Fig." instead of "Figure"? \setupcaptions[numberstopper={.},] changes "Figure 1" to "Figure 1.", but is there a similar key for the text? (\setupcations[prefix=] allows only "yes" or "no" - http://wiki.contextgarden.net/Command/setupcaptions ) Best regards, Lukas -- Ing.
