Right-clicking the Key window or Hierarchy list brings up a quad menu that offers instant access to tools. The menu is context-sensitive, so its contents vary, depending on what is highlighted. For example, when the Hierarchy list is active, you can assign copy and paste controllers, and open properties which you can animate. You can set the Auto Expand and Manual Navigation controls to change the behavior of the Controller window display.
The commands from the alternative quad menu (Alt+right-click) are integrated in the right-click quad menu. The Select, Expand, and Collapse commands are therefore accessible along with the existing quad menu commands, improving workflow efficiency.
