How to replace multiple errors at once.
Imagine you just wrote a long report, but you accidentally typed 'Fare' instead of 'Fair' twenty different times!

Cut, Copy, and Paste mechanisms.
Want to rearrange your document without retyping everything? You need to know when to Cut and when to Copy.
Use Cut (Ctrl + X) when you want to move text. This completely removes the text from its original position. You then use Paste (Ctrl + V) to drop it exactly where you want it.
Use Copy (Ctrl + C) when you want to duplicate text. The original text stays exactly where it is, and you use Paste (Ctrl + V) to create a second copy in a new location.
