I'm not sure I agree with this direction, as this system seems like it has a high cognitive load, that doesn't allow a lot of relegation to muscle memory (ie it seems like you have to keep the feedback loop between your keying and the options that appear open for the duration of the command-invocation), which is what I find attractive about keyboard interfaces in general.
