Pressing the return key will generate a new paragraph.

If you select a heading style for a section of text, the heading style will be applied to each paragraph selected. If you apply bullets to a section of text, a bullet will be created for each paragraph. If you indent a section of text, the indent will be applied to each paragraph in the selected text.

Use paragraphs logically to break your text into readable chunks. Remember that reading text on-screen is hard on the eyes. Plenty of paragraph breaks make the text much easier to read.

Pressing shift + return will create a line break within the same paragraph without any extra line spacing.

Pressing control+end will take the cursor to the very end of the text so you can easily see if you have any spare lines at the end of your text.

Triple clicking will select the whole paragraph.
