Post Navigation

Hello,
I’ve been looking at modifying the next and previous post information in individual posts (modifying the text).
Currently when I open a post, at the bottom, there is the text name of the previous and next posts with arrows.
Instead of the names of the posts, I would like them to read “Next Post” and “Previous Post”. I’ve looked for this is the Aspen admin options, but haven’t found if it can be modified there. I’ve looked at a number of websites to see how this can be modified, but nothing seems to match when I see in the Aspen files.

Any suggestions?

Thank you,

Matt
