Best programming aids for a quadriplegic programmer

I have sports injuries, and I cannot type more than few characters without serious pain.

Instead, I use emacs together with Dragon NaturallySpeaking.I have written macros and scripts to help it get by. The system is not perfect, but it works.I program mostly in C++, but I also use python.

If you want to, I will help you with that.I have to warn you, it takes few months to get used to speech to text software and train it. moreover, I am not native English speaker, am sure that gets in the way

Do not despair, there are solutions.

here a link to emacs and Dragon files (unfortunately have not documented yet)

It's worth looking at the Dasher Project, which makes it possible to enter text reasonably quickly even for the severly disabled. Dasher is built on a probabilistic model of languages, so that more likely utterances are easier to enter into the system. The demonstration system comes with a fairly impressive collection of natural languages. It should be easy to get a large corpus of programs written in Python, load Dasher with the corpus, and create a special-purpose version for entering Python programs.

This isn't part of any professional software, but when I saw this, I've thought it would be good for text entry using eye movement tracking or minimal mouse movement. See Ken Perlin's Processing page, and look at the applets for "pen input".
