Adds SearchReplace editing controls to the visual content editor (TinyMCE).
A light weight plug-in that adds the Search and Replace editing controls from the full version of TinyMCE, optimized for WordPress. Note that this may not work in conjunction with other plug-ins that significantly alter or replace the visual editor’s default behavior.
Note that the SearchReplace controls are contained in the “kitchen sink” toolbar, toggled with the last button on the first row of controls.

MCE SearchReplace Buttons

Adds Search and Replace controls to the visual content editor (TinyMCE).
