1.
Click on the Presentation tab, then click on the Pages tab.

2.
Make sure that you are editing the default page template.
3.
Find the code that looks like the following:
<txp:if_individual_article>
<p><txp:link_to_prev><txp:prev_title /></txp:link_to_prev>
<txp:link_to_next><txp:next_title /></txp:link_to_next></p>
<txp:else />
<p><txp:older><txp:text item="older" /></txp:older>
<txp:newer><txp:text item="newer" /></txp:newer></p>
</txp:if_individual_article>
To change the links so they say something like “Previous” and “Next”, replace <txp:prev_title /> with “Previously” and <txp:next_title /> with “Next”.
Use whichever words you would like to substitute for “Previous” and “Next”.
