In 10.10 that I was using before 12.04 you could use alt+F9 to minimise a window to the task bar. In 12.04 meta+ctrl+ cursor up down maximises and unmaximises a window. If you have a numeric keypad you can use ctrl+alt+0 to minimise to launcher. On my netbook I don't have a numeric keypad and the normal numbers do not work with the above shortcut. How can I minimise windows with a keyboard shortcut?
