I've been adding lists of keywords and alternate spellings to the end to the text of DigiTrad submissions and corrections, when I think of it. We also like to add songwriter information when we can. Just post it, and we'll try to harvest and submit it.
Maybe some day we'll make a major project of adding keywords and making corrections to the DT. Right now, Dick and Susan are mostly involved in adding tunes and in getting out a downloadable version of the DT that will work on newer operating systems.
But if you post suggestions for corrections, we'll do our best to collect them and add them to the DT.
