learning about mc

[Bryce Martin <bryce martin gmx com>]

Hi,

My name is Bryce Martin. I'm Australian and this is my first email to
this list. I'm a Maths and ICT teacher working in Abu Dhabi. 

I want to get better at using MC. I think it is a great software
application. 

Can anyone tell me how to configure MC to open a particular application
to view and edit text files. Currently it is using mcedit which is
fine. But I was wondering how to make configuration changes like the
one I've just mentioned.

I'm using Ubuntu-Gnome. Gnome 3 is totally amazing and I just love it.
MC is a great fit to Gnome. Great softwares both.

Any advice on reading material (books) about MC would be warmly
accepted.

Regards,
Bryce.
