Is it possible to use snippet call in the article content

Articles extra :
Modx 2.3.3

I am using iframe to display article content.

In a new article in the content area

I am using chunk

[[$op_EnvBuilding_ch? &input=`assets/docs/Environmentally_Sustainable_Buildings/Education_paper1.pdf`]]

Problem:
[[+articles]] shows articles list with article content .
I expect it should only to show list of articles to be viewed on the main blog page.



Is it possible to use snippet call in the article content?

Using "Read more" button - work as expected
