As an advanced user all of us spend a lot of time on the terminal which is easier and allows more control on the task, so I was wondering how would it be to have a shortcut key to open the terminal window whenever we want, rather than navigating the menu or clicking some shortcut.
Ubuntu has a built-in tool for assigning keyboard shortcuts. Navigate to System -> Preferences -> Keyboard Shortcuts
Scroll and find where it says "Run a terminal", then click on the shortcut cloumn after which you should see "New accelerator...", now press the key combination you want to set as shortcut.
That's it, I created Ctrl+Alt+T as my shortcut for launching a terminal window. Enjoy!
