Memorizing timing from keyboard inputs?

I pastor NewHopeDeaf and we're trying to recreate worship songs the way we did years ago with Flash. I hope we can do something similar with Presenter.

We would take a master recording, overlay lyrics and save it as a single file. That way in worship we could start the movie, and the Deaf worship leader kept time with the music by the lyrics.

I note that I can adjust the timing of slides in Presenter. What would be far handier is if Presenter can remember cues from the keyboard. That way I could prep a series of lyric slides, attach a master recording, go through the song once and have Presenter remember the prompt to go to the next slide. I'm not seeing how to do this. Is it possible.
Thanks in advance,
Paul
