UNIX for Advanced & Expert Users

I found this to be a confusing subject so I wanted to share what I have learned. I finally figured it out from this website.

vi editor FAQ (Frequently Asked Question List), Part 1/2

You MUST include the single double quotation in this. Obviously <letter> with any letter you feel like.

Code:

"<letter>yy

Another example with deleting text.

Vim documentation: change

In this example this deletes a single letter and puts it in the x register. You do not need the brackets here. They just used them to make the single double mark more obvious.

Code:

["x]x

Like the FAQ..Thanks for sharing.
