"Middle click opens URL in selection" was turned off intentionally in order to 
use middle-click to scroll pages vertically. But while this works normally 
with KHTML, it doesn't with kwebkitpart.

Now I see. Indeed, middle-click doesn't trigger the expected result (vertical 
scroll). However, although "Middle click opens URL in selection" is unchecked, 
middle-clicking with Webkit triggers a similar response nonetheless - I say 
"similar" because if last entry in the clipboard is a URL, rightclicking will 
open that URL within the tab. But if last entry in the clipboard is a word or 
a sentence:

- with "Middle click opens URL in selection" checked on KHTML, I am asked "Do 
you want to search the Internet for [...]?";
- with the "Middle click opens URL in selection" UNchecked on Webkit, instead, 
middle-clicking will automatically show a page with results from Google.

I believe this is not the intended behavior, since I did not initiate the 
search, but merely wanted to scroll the page vertically. According to your 
explanation, though, this feature is yet to be implemented, so it is my 
understanding that it should only fail to respond to any right-click, at that 
point. Hence, I believe this is not a feature request, but a bug that should 
be fixed.

Sorry if my explanation sounds convoluted and lacks any technical knowledge, 
but if you feel it still fails to clarify the issue, please don't hesitate to 
let me know, and I will try to add any missing detail.
