In computing, a keyboard shortcut is a set of one or more keys that invoke a command in software or an operating system.
They are typically an alternate means for invoking commands that would otherwise be accessible only through a menu, a mouse, or an aspect of the user interface. These shortcuts can expedite common operations by reducing input sequences to a few keystrokes.
These shortcuts can provide an easier and quicker method of using computer programs. These commands are commonly accessed by using the [Alt] key (on PC computers), [command key] (on Apple computers), [Ctrl], and [Shift] in conjunction with a single letter.
These shortcuts are for the following programs and applications.
Sometimes you want stuff to run at startup, be it an application or a forced setting. This is fairly easy to achieve in Rasbpian, here’s how:
You can use the Raspbian preferences via the GUI to cause the pi user to be auto logged in at boot up and the GUI to automatically run. However, if you need to run with root privileges due to needing IO pin control (PLEASE NOTE: It is not advised to run as root) then set the Raspbian preferences to boot to the command line. Now open this file by editing it(you can use your favourite editor, for this example we use nano):
sudo nano /etc/rc.local
Before the “exit 0” line in it add the following line:
#Auto run the GUI as root sudo startx
Save it by pressing Ctrl+X, ” Y“, ENTER
Reboot your RPi and it should automatically run the GUI as the root user.

Unfortunately in recent updates, the above has changed in that really annoying way that happens all to often with Linux versions, but seems to be the current file that needs to be edited. It used to be these but they no longer seem to work with the latest version of Raspbian:
