There is a tool you might be used to because you have an Android phone that shows in AutoCAD 2015, and I love it.
It's what I over heard Lynn Allen refer to as "the hamburger". It lives in the lower right-hand corner of your screen and controls all kinds of screen tools. Besides the cool name, it stays open and lets you make multiple changes before closing, unlike its predecessor.
I suppose it is called the hamburger because the symbol can resemble two buns with a hamburger patty in the middle. In the end, it satisfies like famous sandwich, and I am glad to add it to my vocabulary.
