Switch split screen game views in Portal 2 PTI

The console command you are looking for is swapsplit.

To enable the console, start by going to Keyboard settings, enable the Developer Console, go into the binds menu and bind the console to a key you won't forget. (I use tilde `)

Once you've opened the console, type in bind [KEY] swapsplit, replacing [KEY] with the key you want to bind it to. Then hit enter.

In order to make sure this stays between game sessions (Portal 2's a bit weird with that), type in host_writeconfig and hit enter again.

Now, whenever you press that key, your split screen controller should swap!
