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>
