Allow to display comment form inside post, page and widget.
Basically comment is inbuilt feature in WordPress but in some case we need embedded comment form.
Example.
* we need to embedded comment inside post.
* some theme build without comment form for pages or custom post type.
* you want to display comment form for specific post only, so you can disable comment for all page and use shortcode to display comment.
* in custom development you need comment form inside widget.
so here we have comment form shortcode to display comment using shortcode inside post,page or widget.
Comment Form Shortcode Help
You can use below ShortCode in post or page or in widget to show comment form.
[comment comment_file =”/comments.php”]
Here comment_file is optional, if you have custom comment file, you have to pass here.
How To Use : 
[comment]
[comment comment_file =”/short-comments.php”]

Comment Form Shortcode

Scott Reilly

From the admin listing of posts (‘Edit Posts’) and pages (‘Edit Pages’), a user can close or open comments to any posts to which they have sufficient privileges to make such changes (essentially admins and post authors for their own posts). This is done via an AJAX-powered color-coded indicator. The color-coding gives instant feedback on the current status of the post for comments: green means the post/page is open to comments, red means the post/page is closed to comments. Being AJAX-powered means that the change is submitted in the background after being clicked without requiring a page reload.
This plugin will only function for administrative users in the admin who have JavaScript enabled.

<h3>Developer Documentation</h3>
Developer documentation can be found in <a href="https://github.com/coffee2code/one-click-close-comments/blob/master/DEVELOPER-DOCS.md" rel="nofollow ugc">DEVELOPER-DOCS.md</a>. That documentation covers the hooks provided by the plugin.
As an overview, these are the hooks provided by the plugin:
<ul>
<li><code>c2c_one_click_close_comments_click_char</code> : Filter to customize the character, string, or markup used as the indicator used to toggle a post’s comment status.</li>
</ul>

One Click Close Comments

I used that plugin as a perfect utility tool for our documentation pages. 
One click & your work is done. Awesome!!!
Thanks
