Howto do AND in search pattern?

Hello,

        I have a quite a few entries in my .procmailrc, but don't know how to
set it up in such a way that I can shorten it a bit. There are for instance:

"""""""""""""""""""""""""""""""""
:0
* ^From.*dpg-baf
{
    :0 c
    ! elena(_at_)pc-kae
}
:0
* ^To.*dpg-baf
{
    :0 c
    ! elena(_at_)pc-kae
}
:0
* ^Cc.*dpg-baf
{
    :0 c
    ! elena(_at_)pc-kae
}
"""""""""""""""""""""""""""""""""
What I want is something like
:0
* ^\(From \OR To \OR Cc\).*dpg-baf
{
    :0 c
    ! elena(_at_)pc-kae
} 
where I began my fictious commands with a backslash. HOWTO do this right?

Thanks in advance,
Marko
