The answer to your question (about how to raise the arrow below 'lim')
is given in the following lines:
----------------------------------------------------------------------
The limit
\vtop{\hbox{\ital lim}\kern-.2em
      \hbox{\kern-.2em$\longrightarrow\atop\alpha\,\in\,A$}}
exists only when $\alpha$ is a figment of your imagination.


A better (in my opinion) result may be produced with the following:
----------------------------------------------------------------------
The limit
\vtop{\hbox{\ital lim}\kern-.6em
      \hbox{$\scriptstyle\kern.2em\longrightarrow$}\kern-.6em
      \hbox{$\scriptstyle\kern-.05em\alpha\,\in\,A$}}
exists only when $\alpha$ is a figment of your imagination.

These two sets of TeX code work OK, but they are not very elegant.  Things
would be easier if \overrightarrow worked properly within a subscript.
Can anybody else produce a simpler solution?
