I can Fly! (New Rust)!?

I am the admin of a server and I was playing around with some of the env. and giveitem commands and I am not sure what key combo I pressed but all of a sudden I was able to fly, go through walls, rocks, etc.

I did not figure out how to turn it off or back on or land but just go up.

is this a feature of a bug? if its there, how do I turn it on/off and land? as an admin it is a nice feature.

Left Shift + L and you’ll fly around

Left Shift + P and you’ll have a free cam where you can press the space bar to cycle to near by players
