How can I enable the native shortcuts like
- Alt + Ctrl + T: Terminal
- Alt + Ctrl + D: Show Desktop
on Gnome 3.
GNOME 3.4 uses gsettings for the keyboard shortcuts while Ubuntu still uses gconf for the keyboard shortcuts. Because of this, there is no easy way to enable the native shortcuts for gnome-shell.

Move to Custom Shortcuts and add a new shortcut by clicking on the + button. Add a relevant name to the shortcut. Input gnome-terminal for the command and add the keyboard shortcut you desire.

Open dconf-editor, navigate to
If you want other options to use the native shortcuts as well, look for them in the dconf-editor in the sub options mentioned above and modify them accordingly.
