We've long wanted to support Contextual Search in Talkback, etc, for Accessibility.  Maybe we can leverage the last utterance in Talkback to get context and do a search?  Details at this thread: https://groups.google.com/a/google.com/forum/#!searchin/contextual-search-eng/utterance%7Csort:relevance/contextual-search-eng/M2Ja599mwyA/q7etqknQCgAJ

Guessing we might be able to do this for M-55.
