Yes, just click the ? looking icon in the micro menu (default bottom right hand of screen).

I like the new tooltips, especially useful for learning the new combo system. However, while trying to gear my character, the tooltips for equipment completely cover up the window that displays that equipment's stats. So in order to change what my character is currently wearing, I have to turn off the help feature, gear up, then turn it back on to know which abilities I am using. Hopefully this will be changed soon, could easily be done so if the tool tip in the inventory UI showed above the targeted item instead of below it.
