Saving responses for common customer inquiries

I've been searching the KB and I guess I'm not using the correct terms to find what feature I'm looking for. We get tickets on a daily basis that we can reply to with either the same text, or a few variations of that text. Currently we have the text blocks on a Word doc and just copy/paste in the desired reply. What is/are the features in Zendesk I can use to accomplish this? Is this Macros or are there other options? What is the search term I should be using to find this? I'm seeing some AI options, but I'd rather stay manual for now until I can see how it all responds.
