Re: Insert Euro symbol

    A lot of them are inconvenient IMHO since they occur very frequently
    e.g. in writing emails.  What do you think about having sequences of
    three characters?

That might be the best choice for these non-letters,
if Quail works well with three-letter sequences.
But these sequences shouldn't start with a control character.
Quail works on sequences of self-inserting characters.

Could you try defining some sequences and see what this is like
in practice?

I am thinking about what the sequences should look like.
Perhaps they should all start with a common pair of characters.
Perhaps `.,' is a good choice, since that sequence is rarely
used and easy to type.  `.,,' could stand for `.,'.
