emacs for beginners (copy and paste)

[piconese . as]

Hi!!! I'm starting to use EMACS and I'have a problem:

I want to copy and paste the values of alpha_eff delta_eff gamma_eff.

The problem is that I want to do this for 75 movements.

So I want to select and to copy only the values of alpha_eff delta_eff 
gamma_eff for each movement and to paste them in a new file.

Can you help me??

Thanks
