Link to Post

This plugin permits you to easily create a link to an existing content of your site.

TinyMCE has a built in feature to include a predefined list of links to select from. This plugin simply creates a list 
from your pages in WordPress. Create a link like usual in TinyMCE, but you now have a new drop down menu called “Link List” 
where all pages/links are already setup for you.
This currently only works for pages, not for posts.

AWS Easy Page Link

Using the External Link List feature of TinyMCE, this makes it easy to create a link to another page on your website.
