Initially also on Emacs as a minor mode, the concept is to write in a shorthand of greek letters, mapped like to a Dvorak distribution, that stand there as a code, as variables or latent values, expanded upon a key combination to one of several languages: German, Hebrew or Yiddish. Text can stay code-mixed indefinitely. The greek letters are a preform, condensed by layers of translation and transliteration, a hybrid con, and the keyboard layout itself, dynamic and not static, is dual: for every greek letter in the layout correpsonds a hebrew letter or diphtong or diacritic mark etc. It is a merge and disambiguation of both Dvorak/Programmer Dvorak and Yiddish Klal.
I really don't know if it may seem useful to someone, but I've been itching writing a bit jargon in a system like this for some weeks.
