Is there any parameter to Special:ChangeContentModel that similar to wpExtraQueryRedirect in submit action of index.php?
In fact, I asked the same question in Help talk:ChangeContentModel, but I'm not sure that I could get answers in a year. So I ask about it here again. If you want to know more about my question, please go to my previous question as linked earlier.

Thank you for replying, but I didn't mean about GET parameters. I want to know about POST parameters which can use in form. I'm sorry that the question isn't clear.
["pagetitle", "model", "reason", "wpEditToken", "title"] should be the key names
This page is a 2 step form, but if pagetitle and title have the same value and are both submitted at the same time, then it should work as a single step as well.
When I tested, it seems that the "title" key does nothing... When I changed value of it on second step, nothing changed. And even when I deleted the input with "title" name on the same step, nothing changed either. It works well. And I could find "redirectparams" key, what does it? I expected that GET parameters are setted into its value when I send the form like wpExtraQueryRedirect. So I changed its value, but nothing changed.
redirectparams is a feature of special pages that allows extensions to preserve some additional context. You can ignore it.
