If it's a pattern consisting of all backward walks for lady, it's probably either a 3-Step or Feather Step (or both in succession). Ballroomdancers doesn't have silver level yet, but those patterns happen to be beginning bronze in Int'l style, so check Int'l Foxtrot if you want to see video clips of the Three Step and Feather Step.
It's not very typical in American style to dance a Feather into a Twinkle, however. You may be thinking of an Open Left Box, although it doesn't consist entirely of backward steps. This figure, unfortunately, does not have an Int'l style equivalent, so no video clips are available yet.
FYI, "Twinkle" and "Open Right Turn" are not synonyous. An Open Right Turn -- or more specifically, an Open Right Turn from PP -- can follow a Twinkle. But the Twinkle itself is not part of the Open Right Turn. (If you compare the basic Silver combo to the fundamental turn & change combo, the Twinkle is the Silver equivalent to the LF Change which leads into the Right Turn, if that makes sense). If you're an Arthur Murray student, you may have been confused by the fact that their school figure #1, "Open Right Turn", is actually an amalgamation consisting of a Twinkle, 1-3 of an Open Right Turn from PP, a Natural Spin Twinkle (aka Open Impetus), and a Feather ending from PP. This used to be called a "Triple Twinkle", but someone must have pointed out that it only contains two Twinkles, and so they updated the name in their syllabus. Unfortunately, their choice of replacement is more confusing than the original. This has nothing to do with where you might find a video clip, but I thought you'd find it interesting anyway.
