Ubuntu Keyboard Shortcut

1. Switch to the next/previous workspace



If you make use of the workspace very frequently, you can easily switch between different workspaces by pressing Ctrl + Alt + Left/Right Arrow. The Left key brings you to the previous workspace while the Right key brings you to the next adjacent. If you have enabled Compiz, you can even get it to show all the workspace by pressing Super + E on the keyboard.
2. Move the current window to another workspace



By pressing Shift+ Ctrl + Alt + Left/Right Arrow,
you can easily move your current window to another workspace in the
specified direction. This keyboard shortcut works very well with the
one mentioned above. If you have the habit of opening many
applications/windows when doing your work, but don’t like to see your
desktop and menubar cluttered with all the application windows, you can
use this shortcut key to move your applications to another workspace
and get your desktop organized.
3. Show the desktop



Ctrl + Alt + D enables
you to quickly minimize all windows and give focus to the desktop. When
all windows are minimized, this shortcut can also maximize all the
windows to their previous state.
4. Keyboard shortcut for the mouse right-click



In most applications, you can always right-click on the mouse to access the options menu. On the keyboard, you can simply press Shift + F10 to achieve this ‘right-click‘ effect
5. Restart session and recover from crashes



There are very few instances where Ubuntu will crash totally. But if it does, you can press Ctrl + Alt + Backspace to restart the session, and 90% of the time, it will recover from the crashes.
6. Lock the screen quickly



If you need to leave your workstation for a while, you can quickly lock up your screen by pressing Ctrl + Alt + L and prevent unauthorized access by others.
7. Switch between windows in the reverse direction



Alt + Tab is a common shortcut key that allow you to switch between open windows. But do you know that by including the ‘Shift‘ button, you can reverse the windows switching direction? This is useful when you press Alt + Tab too fast and passed the window that you want to switch to. Simply press down the ‘Shift‘ button to go back to the previous window in the switch cycle.
8. Move windows with arrow keys



Press Alt+F7 to activate the Move window function and use any arrows key (up, down, left, right) to move the window around the screen.
9. Show hidden files



Most of the time, you won’t need to view the hidden files in your home folder, but in the event that you need to, you can press Ctrl + H inside the Nautilus (the file manager for Ubuntu) to show all hidden files.
10. Show file properties without right-clicking the mouse
