I am very new to javascript development, although I have a fair amount of experience with .net. I am trying to build a simple custom plug-in for TinyMCE version 3.x . Basically, I want to be able to add a button to the toolbar that:

1) pops up an .aspx page
2) user will make a choice of a video from a list generated by the aspx
3) make some sort of call back to write some kind of placeholder into the tinymce text window.

I will then store it in my database with the place holder in place.

I do not need it to render as anything special in the WYSIWYG editor. The MoxieCode documentation is overly confusion for me and I just can't figure our what the javascript call is to insert text back into editor. Can anyone direct me in a direction or have a simple example? I cannot find any examples that use .net and TinyMCE 3.x.

Any direction would be greatly appreciated. This has really been a sticking point for me on this project.

Thanks,
Brett
