Prevent single word of being edited in a Textarea
<p>Hey guys
What I want to achieve is the following;</p>

<p>I have a textarea filled with text in our CMS. That text contains some special strings that are variable names. In the site these variables are replaced with something else (e.g "$!test;" will be replaced with "Hello this is a test").</p>

<p>Now I want to prevent the users from editing these strings in the textarea, but making the whole textarea disabled or readonly ofcourse has no use.</p>

<p>I was hoping that maybe there are some ways to do this, even if I need a WYSIWYG editor like TinyMCE or CKEditor.</p>

<p>Thanks in advance guys</p>

<p>Cheers!
Maikel</p>
