[erlang-questions] tab-expandable modules in the shell

[Alexander Wagner]

Hi,
I have a potentially silly Question about tab-expand in the erlang shell:
Which Modules are expandable?

On my fresh install of R12B-2 (self-compiled on gentoo) it seems to work only 
for a limited number of modules (a full list is at the end of this email).
I can tab-complete functions in ets, but nothing from mnesia. My own modules 
are missing too (except for user_default). How can I fix this?

I have found no mention of tab-expansion in the online documentation (like 
here: http://www.erlang.org/doc/apps/erts/tty.html )

PS: 
hitting tab in a fresh erl shell gives me this
