IANACR, but I would think it's not practical, in that the stenotype keyboard (the official term for the keyboard used by court reporters) is used to record the phonetic _sounds_ of what is being spoken, rather than the actual words. These phonetic codes do not resemble anything approximating the actual words they represent.

Also, computer source code (whatever the language) typically contains variable names which often are (a) typically case-sensitive, and (b) abbreviated or even single characters. And even the basic syntax of the chosen language may not be easily capturable via phonetic sounds, what with open and closing parentheses, curly braces, square brackets, etc., and compound reserved words with prefixes (such as #foreach in Velocity template language).

Again, IANACR, but I don't see how it could possibly work...

I seem to remember reading once that what is typed by a stenographer is also only meaningful to them. And therefore must be transcribed into English later by the same stenographer.

Can anyone here confirm that?

I wonder how far programming-specific chorded keyboards could get. Like you usually only have a handful of variables in a function or method. I bet, at least, all the extra context provided by object oriented languages could be used to help the keyboard provide us meaningful suggestions.
