Sending info to vB editor

[The Geek]

Hey guys, Im praying someone can enlighten me here.

Basically, I am trying to port over my vba Gallery Popup which allows users to insert images from their vbaGallery into their posts. I have it ported except for the text insertion part. I cant seem to find where the heck im supposed to be inserting the text.
The old message editor was something straight forward to access. Can anyone point me in the right direction to do the same with the new set up?

it basically needs to be something like:

window.opener.editor.innerHTML = "blahlablhasd";

Of course, this depends on the editor currently in use (anyone know how to determine which one is in use?)

The new model is obviously very powerful, but very complex and difficult to follow. I have spent hourse trying to figure this out and now I am going to go crawl up under a rock and cry

Thanks in advance!
