So basically I had one of my famous tantrums and ended up throwing a spongebob squarepants toy I got from burger king years ago at my MBP's screen. I can't see anything from one side now, so I hooked an external monitor onto my MBP with the hopes of still being able to use it. It worked, the only problem is that i'm having trouble making my external monitor my primary screen. Is there any way I can switch my external monitor into primary? Keep in mind I can't see through a little less than half of my original screen, so any special tab commands to open something up would be greatly appreciated.
