I really want to make the toggle full screen button on the boarder corner work, like the one next to the X. Is there a way to do that?

I'm brand new to programming, and entirely self taught atm. I'm trying to read the Lua reference Manual, and I find it extremely confusing. I feel like I need a tutorial on how to read it.

Does anyone have suggests on things I need to do or learn so I can actually understand the manual?

The only experience I have with game engines (or coding really) is messing around in scratch. There's a feature on the sight where you can make clones of a sprite, and they'll be another object following the same code as the original sprite.

I was wondering if there was a way to do the samething or some equivalency in Love2d?
