I would probably do okay at this. But I know some good people who would not. One of them is nearly blind, and is one of the best systems programmers I know. Since I use Emacs nearly exclusively (Visual Studio for debugging, and other tools for writing documentation), I would revert to "I have to type code in a dumb editor" mode, and my fingers would be stupid. You'd see some stumbling around. I'm not sure it's useful knowledge for the interviewer.
