For sure, whether the API behaves in a platform specific manner or not, web applications can get the other behavior if they need it.  I suggested the spell checker only as an example, suggesting that not all possible users of the API want to simulate user's keyboard events.

I mean the API having the same behavior no matter what platform the UA is running on.  Or, another way to put it, the web application getting the same behavior from the API no matter what platform the UA hosting the web application is running on.

No, since its behavior changes based on which platform the user viewing the web page is running at the moment.

Do you know more details on this?  Which commands have this platform specific behavior?  And why does Webkit do different things on different platforms here?
