Thank you. Pretty cool package.

Using hyperref package it is possible to make a box, which appears after hovering text. E.g.: \href{mailto:user@domain}{user@domain}
Is it possible in Latex to make such a box over normal text, which isn't a reference, hyperlink or something like that?

I could be wrong, but I don't think it is possible to use variables of any sort in new command declarations (...)

It is possible. I create "dynamically" commands this way:

\newcommand{\addnextcommand}[3]{
\stepcounter{counter}
\expandafter\newcommand\expandafter{\csname basename\roman ...

Oh boy, READ CAREFULLY, if that was so simple, I wouldn't bother u. :P
I wrote that a set of commands theoretically can be infinite.
You solved problem for my simple example. What if there will be 200 of such defined commands? :P I can't know that number! That is why I need to concatenate command ...

How can I concatenate a base name of my command with something returned by counter?
These are defined commands (theoretically may be an infinite set):
\basenamei
\basenameii
\basenameiii
I'd like to call one of them depending on what is returned by \roman{counter}.
How can I do it?
