Gnome hotkeys

GNOME is a desktop environment and an international project that includes creating software development frameworks, selecting application software for the desktop, and working on the programs which manage application launching, file handling, and window and task management. GNOME is part of the GNU Project and can be used with various Unix-like operating systems - most notably those built on top of the Linux kernel and the GNU userland.
