So i will put known controls here so more noobs can see! please comment the controls how to do other things i have not listed, i am fairly new myself.

Pick up dead animals and eat them to scan them, not sure if it works when you are full.
Hold shift while holding a dead animal to eat it, works on predators such as lizards!

C to open menu, to use menu somewhere will be a box that moves as you mouse does, it may not align with your mouse but it is the selector, under a drone will be three options, Auto, Attack, and stay. Use the selector to choose what mode you want your drone to be in, Auto means idle, they will follow you and use it's ai to detect if it should fight or not, auto-matically. Attack basically means go into fight mode, they will fight predators, i'm not sure exactly if going in this mode makes them look to fight by attacking predators in the room or it makes it do more damage, let me know in the comments! stay means to follow you, do not initiate fight under any circumstances.
