[Plugin: TinyMCE Advanced] Adding a plugin to TinyMCE advanced

Hello all. I need to add a plugin to TinyMCE advanced, but I don’t even know how to add a plugin to regular tinyMCE! Foolish, I now, but we get ourselves into some strange predicaments, don’t we?

I feel like it should be pretty easy, as plugins go. I need a button that inserts a string at the cursor. In this case, let’s say the string is ‘{BREAK}’. Any tips or direction to go in would be appreciated.

Thanks, Joe
