# (naming modules after builtin functions is not such a hot idea...)
# an KeyTrans instance translates Event objects into Command objects
# hmm, at what level do we want [C-i] and [tab] to be equivalent?
# [meta-a] and [esc a]? obviously, these are going to be equivalent
# for the UnixConsole, but should they be for PygameConsole?
# it would in any situation seem to be a bad idea to bind, say, [tab]
# and [C-i] to *different* things... but should binding one bind the
# other?
# executive, temporary decision: [tab] and [C-i] are distinct, but
# [meta-key] is identified with [esc key]. We demand that any console
# class does quite a lot towards emulating a unix terminal.
