Answer:

Rule 1: Within a paragraph, just keep typing

When you use a typewriter, you have to use the carriage return at the end of every line. When you use a word processor, such as Word, you just keep typing. Type type type. Word knows where the margins are. You can see the margins, too: the dotted rectangle on the page shows you where they are. Just keep typing and Word will wrap the text within the margins.

Don't press Enter at the end of every line. Press Enter to indicate the end of a paragraph, not the end of a line.

Make sure you can see when you have pressed Enter

OK: So there's this BIG rule that says "don't press Enter at the end of every line". But, you say, I can't see whether I've pressed Enter or not. So what's the big deal? This section explains how to see when you've pressed Enter.

Just as an experiment, type some text in Word, then press Enter several times. Your document might look something like the example below.

This is some text¶

¶

¶

¶

¶

Can you see the effect of having pressed Enter several times? Your machine may not have set up Word to show you. If you can't see the ¶ signs, click the ¶ button on the Standard Toolbar or on the Home tab. The ¶ is a symbol meaning the end of a paragraph. Word will show you where you have pressed Enter by displaying this symbol. The symbol doesn't print. It's just there to enable you to see what's going on.

You can DELETE a paragraph mark in the same way as you would delete text. You can press Backspace to reverse over them, or use niftier ways that you'll see in later Basic Concepts pages.

(If you clicked the ¶ button and you don't see ¶ signs in your document, choose Tools > Options > View. Under the heading "Formatting marks" click All.)

You pressed Enter several times. Now you can see that you pressed Enter several times. You may ALSO be able to see the spaces between words displayed by a dot. This is also useful, as you'll see below.

Rule 2: Press Enter once at the end of every paragraph

When you use a typewriter, you use the carriage return twice at the end of every paragraph. This gives you the desired spacing between paragraphs.

In Word, you don't do that. You press Enter once at the end of a paragraph.

Rule 3: Use the spacebar once at the end of each sentence

On a typewriter, lots of people put two spaces after a full stop (period, for the Americans amongst us) or exclamation mark or question mark that ends a sentence.
