Where is Find Tag/Attribute?

I don't see this in version 5.4 and I thought it was implemented by this version? I updated to the latest release M170. I need to be able to search for a particular element by name and attribute value. Even searching the markup for the attr value would suffice, but checking Match Markup in the f/r dialog options does not work. I could have my doc writers create bookmarks but that is less than ideal.
