Excellent.  The only "personal" thing I see about it is that you might
have picked aliases based on personal preference.  But there is no
reason why the concept of giving such aliases is personal.  That is a
generally useful idea.

Indeed, that is one part of the suggestion.  The part 2 of the
suggestion is to allow key bindings for such aliases, which would then
be widely applicable across several modes.

Do you mean you already have such an aliasing scheme?  I suppose one
can dispatch on the major mode.  That is neat!

It is not a general solution, of course, since it is based on a closed
world assumption about what modes one needs to deal with.  But it is a
good starting point.

So, I suppose you will let dired-mode do all its self-righteous key
bindings and then use a hook to overwrite all of them with your own
key bindings?  I think I am beginning to like this
software-as-the-enemy principle!
