Have you ever been making something in the workshop and accidentally hit f and your camera gets shoved really close to a brick? I found out how to use this in a good way. If you want to get to places quickly in multiplayer you can click on a brick in that area then hit f and it will teleport you to that area. Cool right! Now if you want to go to places that have no bricks in it in multiplayer all you have to do is get out the first brick you see, move it to where you want to go, hit f, and then delete the brick.
