questions about microemacs on Z

I'm having a hard time finding documentation specific to the Zaurus version
of microemacs. Years ago, I used microemacs all the time, until NTEmacs was
available. I have a few questions about Zaurus emacs:

1. What's the difference between me and mec? It looks like me ignores a
filename given as a command line argument, and mec ignores the guest.emf
setup file. I'd like to have something that pays attention to the setup file
and accepts a filename as an argument to edit that file directly.

2. Shift-fn is the equivalent of Alt, right?

3. Does anyone know of an emf file that maps the keystrokes a little closer
to GNU emacs? 

4. Is there any way to run a microemacs session and the bash terminal
separately and switch between them? So far, it looks like I can only start
up a terminal window and run microemacs in it, and if I try to start up a
new terminal using its icon I just get switched to the running one. 

thanks,

Bob
