Oh, I understand you now! I know of two ways of doing it:

1. Put the command < bolckquote> before you start your quote and end it with </ blockquote> (without any spaces in between)

2. And this is the easier one which I prefer to use as it needs only one key to be pressed. Just key-in ">" before you begin to quote ....and that's it. This one symbol is enough. To discontinue the quote and coming back to your writing, you may need to put a couple of "Enter / Return" keys.

Hope you get it. Try it and let me know if I was not clear enough. Thanks for your interest in learning this!
