Removes those extra-tempting but extra-problematic buttons from tinyMCE, like font color, alignment, and other things that will wreck your style sheet.
In addition, it removes “Heading 1” from the role dropdown, as there should never be more than one H1 on a page — and the page or post title is already it.
<h4>Why Does Formatting Matter?</h4>
When people first get their hands on that shiny WordPress text editor, they often get swept up in the excitement of styling their text. “This is important, so I’ll make it red! And this part will be centered, and this part will use giant letters!”
But as fun as this is, there’s a way to use the WordPress text composer like a pro, and the benefits of doing it in that way are big:
<ul>
<li>Better potential rankings on search engines (Search Engine Optimization)</li>
<li>A consistent look across your whole website and other materials (research shows that visual consistency leads to trust)</li>
<li>Better flexibility across different devices, from desktops to mobile phones</li>
<li>Better accessibility for readers with a wide range of disabilities.</li>
<li>Better maintainability when it comes to future site updates — that means savings!</li>
<li>What’s the secret sauce that provides all these benefits?</li>
</ul>
Mark your text with what it is, not what it should look like.
<h4>What does that mean?</h4>
It means that your website already has a style guide built into it, so that it knows that a subtitle looks a certain way — perhaps it is larger, bold, or a different color than the main text. So when you type in a subtitle, you only need to let WordPress know that it’s a subtitle, and the rest will be taken care of. Do not give in to the temptation to mark the subtitle text as bold, larger, centered or a different color from the WordPress editor.
This plugin removes the most damaging buttons from the WordPress editor, so you (or your clients) won’t be tempted to use them.

Remove Problematic Formatting Options From tinyMCE

Removes those extra-tempting but extra-problematic buttons from tinyMCE, like font color, alignment, and other things that will wreck your style sheet …

Michael Aronoff

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.
NEW 
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>
