You need to use the accessibility APIs for this, that is, the ATK interfaces that are implemented by the accessibility objects in WebKitGTK+, for which you first need to get the AtkObject wrapping the web element you're interested in. Calling webkit_web_view_get_accessible() gives you the AtkObject for the WebView, and then you can go down in the a11y hierarchy by means of AtkObject's methods. Regarding to how to manipulate the caret, in your case you should use the functions from the AtkText interface that allows you to get and set the caret for a given element in the accessibility hierarchy implementing that interface (e.g. a paragraph, a link, a label, a text entry...): atk_text_get_caret_offset() atk_text_set_caret_offset() If you want to know more detailed information, such as where the next word starts, or where the current line ends, you need to use one of the following functions first, specifying the right value for the AtkTextBoundary parameter: atk_text_get_text_before_offset() atk_text_get_text_at_offset atk_text_get_text_after_offset() Not sure if there's a better way to do that, though.
