MDN Site Search

Search MDN using one or multiple keywords...

Do you want a DuckDuckGo bookmarklet?: do a site search of Mozilla Developer's Network based on text you highlight on ANY webpage...
How? Create a bookmark, and then go back in to edit the URL, replacing it with a cut-n-paste of the long javascript one-liner below. Rename the bookmark to something like "MDN Site Search" (I put it on my links bar named as 'MDN'.) Now, in a browser while looking at documentation, or on another learning site, just highlight a keyword or phrase on the page, and select the MDN bookmarklet. It will return a list of all content from the MDN Site related to that highlighted keyword or phrase. Enjoy!

javascript:(function()%7Bq=document.getSelection();%20if(!q)%7Bvoid(q=prompt('MDN%20keywords:',''))%7D;%20if(q)location.href='https://duckduckgo.com/?q=site:developer.mozilla.org%20'+escape(q)%7D)()

DISCLAIMER: I do not have any affiliation with DuckDuckGo whatsoever, I just prefer their privacy policy over googles, and would rather not be tracked while browsing. I recommend their search to everyone I know as the "safer" alternative. You can easily change "DuckDuckGo" to "google" in the location.href string if you would rather use google. It should still work.
