How to add a custom button to the toolbar that calls a JavaScript function?

Question

I'd like to add a button to the toolbar that calls a JavaScript function like Tada()?

Any ideas on how to add this?

I am in the process of developing a number of custom Plugins for CKEditor and here's my survival pack of bookmarks:

• A StackOverflow post linking to and talking about a plugins tutorial that got me started (Tim Down already mentioned this)
• A number of ready-made plugins for FCK and CKEditor that may improve one's understanding of the system
• The Blog of AlfonsoML, one of the developers, lots of valuable stuff there, e.g. Plugin localization in CKEditor
• Interaction between dialog buttons and a IFrame dialog, with input from Garry Yao, one of the developers
• The forums are not as bad as they look, there are some hidden gems there. Make sure you search there, well, if not first, then at least second or third.

For your purpose, I would recommend look at one of the plugins in the _source/plugins directory, for example the "print" button. Adding a simple Javascript function is quite easy to achieve. You should be able to duplicate the print plugin (take the directory from _source into the actual plugins/ directory, worry about minification later), rename it, rename every mention of "print" within it, give the button a proper name you use later in your toolbar setup to include the button, and add your function.
