The composer window has the Wowhead button that inserts shortcode.
I have created Wowhead Shortcode that enables you to insert any World of Warcraft item with just one click.
No need to meddle with “urls, rels, hrefs” in html code every time you want to link an item.
All you have to do is type in the item number you want to display in your post. That’s it!
If you want the shortcode to work with bbPress Forums (since bbpress is a plugin and not part of core WP) you’ll need to activate the shortcode function for it.
Easiest way is to use THIS PLUG-IN .
After you install and activate the plugin, the wowhead tooltips will work in bbpress forums as well.
