The Ubuntu operating system is to replace its application menus with a "head-up display" (HUD) box.
Users control the HUD interface by typing in the command they want carried out.
Developers of the Linux-based software say they will initially offer the HUD as an option, allowing users to "hide" their menu bars.
They say that using the HUD is faster than "mousing through a menu" and makes applications feel more powerful.
