YouTube search bookmarklet — it opens a new window with the selected (highlighted) text as the search term in YouTube. There may already be stuff like this out there, but none of the ones I found seemed to work for me — I wanted something that opened YT in a new window/tab — so I just went ahead and rolled my own.

The basic code is more or less identical to the other bookmarklets you’ve seen here.

Anyway, here it is — link and source code.

• YT
• ユチュ
• ﾕﾁｭ
• ﾕﾁｭ検！
• javascript:(function(){var w=window,d=w.document,s="";;if(d.selection){s=d.selection.createRange().text}else if(d.getSelection){s=d.getSelection()}else if(w.getSelection){s=window.getSelection()}window.open("http://www.youtube.com/results?search=Search&search_query="+encodeURIComponent(s),"_blank")})()

Just for kicks, here’s one for NicoNico video — Japan’s very own YouTube — as well.

• NC
• ND
• ニ動
• ﾆｺ検！
• javascript:(function(){var w=window,d=w.document,s="";;if(d.selection){s=d.selection.createRange().text}else if(d.getSelection){s=d.getSelection()}else if(w.getSelection){s=window.getSelection()}window.open("http://www.nicovideo.jp/search/"+encodeURIComponent(s)+"?track=nicouni_search_keyword","_blank")})()
