Hello, I'm playing with shortcuts now, and I found some limitations on the
current implementation.

It's impossible to re-define shortcuts other than <>; the reason is that, once I
issue

\defineshortcut [()][a][style=\overstrike]

I cannot issue

\defineshortcut [()][b][style=\underline]

later because an "undefined control sequence" error is issued.

(the problem is not present for <> because for them you can use

\defineshortcut [a][style=\overstrike]
\defineshortcut [b][style=\underline]

and <> do no appear again)

Second problem: ligs fail in some cases (if I \defineshortcut
[--][o][style\overstrike] then the following lines misses a few beats:

it seems -o:to work- well--does it?---really?

Third problem: math fails too:

$(a+b)/(a-c-d)_{a+b}$

with -- and ++ defined as shortcuts fail (not on parenthesis, if I make those
active too; depends on the fact that parenthesis are delimiters in math mode?)

(possibily this depends on shortcuts not being nestable); the latter is maybe
more important.
