Mac: Some terminal and Unix/Mac shortcuts

Here I will give you some interesting shortcuts, that every one of us need when working on daily bases with unix or mac and their terminal:

1. Up/Down arrows:
   Preview previews commands. It saves your time when you need the previously typed commands again and again for execution.
   
   
2. control + a:
   Moves the cursor to start of the line. It is very useful when you got a long line about fifteen chars or more, and you need to move to the start of the line or close to the start of the line to do some changes, this shortcut will move you to the start very quickly instead of returning character by character.
   
   
3. control + e:
   Moves the cursor to end of the line. So you can remember that by "a" for alphabit and "e" for the end.

   Moves the cursor to the click point.
