This plugin adds a “Edit” button to your published comments on the site. And allows unregistered users of the site to edit and delete their comments.
You can prohibit the deletion of individual comments and change the appearance of the Edit button.

mi13 comment user edit

This plugin allows guests to edit their comments on your site.

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
