A single newline has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function.

But an empty line starts a new paragraph.

You can break lines<br />
without starting a new paragraph.

• Lists are easy to do:
  • start every line with a star
    • more stars means deeper levels

1. Numbered lists are also good

• One item per line, no hard NEWLINE.

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

• This is primarily for displayed material, but is also used for discussion on Talk pages.

IF a line starts with a space THEN
  it will be formatted exactly 
    as typed;
  in a fixed-width font;
  lines won't wrap;
ENDIF
this is useful for:
  * pasting preformatted text;
  * algorithm descriptions;
  * program source code;
  * ASCII art and chemical structures;

WARNING If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.

• First letter of target is automatically capitalized.
• Internally spaces are automatically represented as underscores (typing an underscore has the same effect as typing a space, but is not recommended).

• You can create it by clicking on the link.

• To create a new page:
  1. Create a link to it on some other page.
  2. Save that page.
  3. Click on the link you just made. The new page will open for editing.
• After creating a page, search for its title and make sure that everyone correctly links to it.

[[How to hack gentoo]] is a page 
that doesn't exist yet.

Redirect one article title to another by putting text like this in its first line. Note that redirects to sections do not work yet. #REDIRECT [[example#example]] will redirect to the example page, but not to any particular section on it. It is possible this feature will be implemented in future, so such redirects could be used now for future compatibility.

Emphasize, strongly, very strongly.

• These are double and triple apostrophes (single-quote marks), not double-quote marks.
• Note that on almost all browsers, these appear as italic and bold; for semantic reasons, <i> and <b> are preferable in mathematical formulas.

''Emphasize'', '''strongly''', 
'''''very strongly'''''.

Superscript: x² or x²

• The latter method of superscript can't be used in the most general context, but is preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

• &nbsp; also prevents line breaks in the middle of text, this is useful in formulas.
