*(Digammas? Digammai? Digammata?)*

[This question](https://latin.stackexchange.com/q/7268/406) revolved around a dialectal form that I'd never seen before. Normally when encountering a new Greek word, Attic or otherwise, my first instinct is to look it up in [Perseus](http://www.perseus.tufts.edu/hopper/morph).

However, the input guide on Perseus doesn't list digamma. Is there a better way to look up a word like Aeolic *ϝε*? (I'm not even sure if LSJ include forms like that.)
