Pklease restore the VoiceOver "magic tap" comm'and.

VoiceOver has a so-called "magic tap" command, a 2-finger double-tap which stops and resumes playing of any media. This used to work perfectly in this app, but it got broken in the last update. Please could you look at restoring it? Without it it is really inconvenient for a blind person to quickly stop the reading of a book and one has to fiddle around to find the Pause button. I would really appreciate it if you could fix this. What a wonderful app!
