Since we spend so much time at the command line in Ubuntu, it sometimes makes it simpler to launch a new terminal window with a shortcut key.

When you see "New accelerator…", the next keystroke that you use will set the keyboard shortcut. I assigned Ctrl+Alt+X as mine…. one press of the key combination and up pops a terminal. What a time saver!
