I am an Emacs lover. Here I admit it :-). One of the things I loved about my previous days with Mac OS X, was the Emacs keybindings (shortcuts) when editing text. CTRL-A, CTRL-K, CTRL-E are some I can't live without when editing e-mails and text docs. If you want to enabled Emacs keybindings (shortcuts) in Ubuntu 12.04 (Unity or GNOME3) just open a Terminal and paste the following line: gsettings set org.gnome.desktop.interface gtk-key-theme "Emacs" Enjoy!
