If you want to embed YouTube videos in your posts but don’t want to copy the embed code every time, this plugin is here to help. 
This plugin integrates with the default WP editor (TinyMCE) and creates a YouTube button that can be easily used to embed YouTube videos. 
The only thing you need to embed a video is its URL. Any URL will do the job (long or short format).
Enjoy this simple yet useful plugin which takes you one step towards easier blogging.

TinyMCE YouTube Embed

This is a plugin for the default WP editor (TinyMCE) that allows users to easily embed YouTube videos in their posts.

This plugin solves one of my greatest annoyances. Quickly changing the case of selected text. Clients often send text with all caps or no caps and clicking through a ton of text to fix the case is often tedious work. I created this simple but effective plugin to eliminate that chore.
Based on a request I have added a fourth button to add Sentence Case as well. So if you have a large block of text with . ? or ! between sentences it will Cap only the first letter of each sentence.
There is an Options Page to enable or disable any of the buttons.

I have also added keyboard shorcuts! 
Ctrl+Shift+L = Lowercase 
Ctrl+Shift+U = Uppercase 
Ctrl+Shift+S = Sentence Case 
Ctrl+Shift+T = Title Case 
(I do not own a mac to test on but command should work according to the TinyMCE documentation)
<h3>Usage</h3>
Highlight the text to be changed. Click the Visual Editor button inside your post/page for the desired effect:
<ul>
<li>UC – Changes selected text to all Uppercase.</li>
<li>lc – Changes selected text to all lowercase.</li>
<li>Sc – Changes selected text to all Sentence case.</li>
<li>Tc – Changes selected text to all Title case.</li>
</ul>
