If you have been an admin for any length of time, you have certainly discovered situations where a server spikes in CPU use or memory utilization and/or load levels. Running `top` won’t always give you the answer, either. So how do you find those sneaky processes that are chewing up your system resources to be able to kill ’em?
Linux distributions like Ubuntu open the main menu with Alt+F1 instead of the Windows key that most new Linux users would be expecting, but it used to be simple to change the shortcut key. Since Ubuntu 9.10 the process isn’t so obvious, but we’ve got the instructions for you.

If you often use removable USB devices like a flash drive, you are probably already familiar with the “Safely Remove Hardware” icon that sits in the system tray. The problem for many people is that the icon is tiny, and clicking it just right to bring up the menu is a pain. Can’t we just make a shortcut to bring up the dialog?
