What it does?:

It allows you to move up and down in the air and slide through doors or walls.




Avoiding being disconnected:

When you have moved up or down in the air, you have to jump not to be disconnected.

Moving up in the air and then sliding north/west/south/east will also disconnect you.



Sometimes when you hold the slide button for more than 5 seconds you can disconnect.

Moving from water to land (example under a bridge) will disconnect you.
