Lightbox JS for WordPress

Hello,

I’m fairly new to WordPress and I was able to install the Lightbox JS plugin. Works wonderfully, except that I don’t see a Lightbox quicktag per the instructions:

“A new button called “Lightbox JS” will be insert into your quicktags editor”

I believe that I am using the default editor and it shows a bar at the top with B, I, etc. but I don’t see the Lightbox JS.

Any suggestions?
