One of the new features Ubuntu MATE is experimenting with for the upcoming 17.10 release is a global menu with HUD support. The HUD, which was a popular feature of the Unity 7 desktop, allows users to search quickly through an application's menu without taking their hands off the keyboard. The user can tap a short-cut key and type the name of the function they wish to use. A demonstration of the HUD at work can be found in the release announcement for Ubuntu MATE 17.10 Alpha 2. "This is something we started during Ubuntu MATE 16.10 and never perfected, but is now ready for prime time. A favourite of Unity 7 users is the Heads-Up Display (HUD) which provides a way to search for and run menu-bar commands without your fingers ever leaving the keyboard. So if you're trying to find that single filter in Gimp but can't remember which filter category it fits into or if you can't recall if preferences sits under File, Edit or Tools on your favourite browser, you can just search for it rather than hunting through the menus."
