how to abbrevate multiple lines?

[frank wang]

Hi,
I want to abbreavte multiple lines into a simple command. Could
someone hlep me how to do it? I searched online and only found the
help to abbrevate a single line.

For example, I need to type this line a lot
{{"abs"},
{ _,_,_,_,},
{ a,b,c,d},
}

Can I abrevate it into a simple command?

Thanks

Frank
