Quick question:

I have a text game and I would like to control the speed of the delay between prints with 3 buttons (Slow, normal, and fast). However, I don't know how to get the game to see the user CHANGE the speed in the MIDDLE of the game. It stays with whatever was initially selected.

I know you can't fix my problem specifically without seeing my code, but if you wanted to setup something similar, what technique/plan would you use?
