Using the keyboard and mouse for one button

Sorry if this is kinda confusing but I’m about to go crazy trying to figure this out.

I’m working on a presentation for work. I have a control pannel at the bottom which allows you to go to any frame that you want. That works fine,but the boss wants to be able to just hit the space bar and it goes to the next frame. This is the way that I have the scripting set up for each button, I don’t know if I need to change it or what. I know its probably really simple but my mind is so gone right now. Thanks a bunch
