next and previous post titles on current post page

I was looking at this site –
https://www.twitchfilm.net/ and if you click on one of the articles you get links at the top that link to the previous and next articles in succession by those articles titles for example
https://www.twitchfilm.net/archives/002814.html

and I was just curious if anybody knew of a way to do this?

I ve been looking at he codex and support forums for some tags or something that could be put into the index.php but im new to wordpress and iam having some trouble – any help would be greatly appreciated
