If you're playing a song in C# (or Db for the Technologically Advanced), try this just before you play your root chord:
Left Hand - Ab, F#
Right Hand - C, E, B (and walk that last finger) A, Ab, F#
(You can just hold A flat with your foot if you're on the organ!)
Then, go to your C# chord. I found this simply "fooling around today after work". It would actually sound cute in a praise and worship song just before everyone got ready to sing! I can take a nap now because that little bit makes me feel like I've learned something and now my brain hurts. WOW!
