Pause keyframe- -help, please

Hello Kirupians. This may or may not be an easy question, so please bear with me.
I need to a keyframe to pause (for say 20 seconds) when the frame is entered (i.e. not a button press, etc). After the 20 seconds is up, i need the timeline to continue playing to the next keyframe.
I’ve searched and searched for setinterval and the like, but i could not find a clear answer. If you could possibly take 3 minutes out of your time to help me out, i’d love you. :slight_smile: Take care.

Victor.
