How I can detect that there was a change in the rich text editor in the Edit Post page?
What I want is to execute a function when the user typed something in the rich text editor (HTML and Visual panes).
I accomplished that in the HTML pane associating a jQuery keyup event in the hidden textarea that tinyMCE create, but still I've not been able to detect user input in the Visual tab.
I'm using WordPress 3.2.1 and I know that they are using tinyMCE for the rich text editor functionality.
Seems that tinyMCE uses an iframe to build the Visual tab in the rich text editor, so I tried the examples pointed here without any results.
Any help appreciated.
