Looking for a multiple editor

[Linux for blind general discussion]

I have a number of texts in which I wish to make alterations that are the same for all of them. I think that there is a linux program in which I can list the alterations and them have them made.
but I can't remember what it is called. Please refresh my memory.

thanks,
John
