 ## `//srel <axis1> <length1> [<axis2> <length2> [<axis3> <length3>]]`
-Short for _select relative_. Sets the pos2 at set distances along 3 axes relative to pos1. If pos1 is not set it will default to the node directly under the player. The axis arguments accept `x, y, z` as well as `up, down, left, right, front, back`. Left, right, front and back are relative to player facing direction. Negative (`-`) can be applied to the axis, the length or both. Implementation by @VorTechnix.
