I have decided that I will model the keyboard interface for Hexxed on vi.

I know that is not what many/any coming from outside the Unix world will expect, but then there are plenty of Hex editors out there and I want to make one that will appeal to at least one niche.

As I instinctively type “:w” in all sorts of places these days, I think there will be some other people out there who might like that sort of functionality too.
