Emphasis

Standard Markdown allows you to do some basic formatting, for example making text italic or bold. Bold and italic is about as much formatting allowed in standard Markdown. Various Markdown implementaions over time have come up with different extensions. P4 implements a number of them.

By surrounding text with specific punctuation marks, you can do the following formatting. You can choose whichever style you prefer, the only rule being is that the same character must be used to open and close an emphasis span.

Use * or _ for italic text:

Use ** or __ for bold text:

Use ==to highlight:

Use ~~ to strikethrough:

Use ++ to underline:

Use ^ for A^superscript or A_subscript:
