Action by numbers

This seems like such a simple task but I seem to be going about it wrong. I want to be able to toggle on and off different movieclips in a scene with an assigned number like: 1 would make movieclip1 start and stop, 2 would make movieclip2 start and stop, etc. I got it to work with the spacebar but with that I can’t target specific movieclips. Any ideas? Thanks for your wisdom!
