How to open quickly – in a browser – a Wikipedia URL from Dictionary or from the 'Look Up in Dictionary' service dialogue?

Question

Example

Either:

• in Dictionary, I am at the Wikipedia page for something; or
• in a Services-capable web browser such as Safari I select a phrase, then use the contextual menu to Look Up "…" (and that thing is found in Wikipedia).

Aim

Open the Wikipedia URL in the web browser. Ideally in a new tab or new window.

In the past, I could do so quickly – without multiple steps.

In Mountain Lion now, I can't do so. I doubt that the feature/routine is lost … more likely forgotten by me (I have used Mountain Lion for a few months, but I can't recall when I last used the Wikipedia routine outlined above).

Question

How can I open quickly – in a web browser – a Wikipedia URL from Dictionary or from the Look Up "…" dialogue?

Answer 1

In Dictionary.app at the foot of the page there's an option:

• View web page.

This is not the routine that I recall.

Also the URL is not what's required – example: I want http://en.wikipedia.org/wiki/Parity_bit but Dictionary links to http://en.wikipedia.org/w/index.php?title=Parity_bit …
