http://askubuntu.com – I am using Ubuntu 11.10, and really satisfied with the Unity. But there is one thing annoying me. If I click the Home Folder button on dash, and for example I want to copy some files from one folder to another. Then I click the Home folder again, but it will bring me to the previous folder not open a new Nautilus explorer for me. And for the terminal, I can always press Ctrl+Alt+T to open a new window. So I'm asking, is there any shortcut or any way to achieve it? (HowTos)
