Tooltips in Unity Editor

Is there a way to have visible tooltips similar to the ones in Blender? I would like to have tooltips on the elements of the editor, like "GameObject.transform.position" when I move the cursor over the position component of my gameobject. I know that there is a way to show tooltips of my variables by modifying the c# script, but I want them about the editor elements. Like it's shown in this video: https://www.youtube.com/watch?v=AqwyETgRI4g
