creating two loops?

Right now i have the main void loop() running down a counter in seconds and displaying it through a lcd. I also have a msg panning at the bottom. I want the message to pan at a higher speed without increasing the countdown. How can I loop at two diffferent delays?

These libraries will help you executing code at different intervals:
TimedAction
Metro

They both use the millis function to handle timing.

You can also just have two counters incrementing in the main loop and calls to different functions once they got over a certain value. Your 2 functions can then reset them to zero before returning to the main loop.
