From version 0.25 the following examples is legal:

**bold** and //italics//
^^superscript^^ and ,,subscript,, 
--deletions-- and ++insertions++

And will produce the following:

bold and italics

superscript and subscript

deletions and insertions

The two last ones are used instead of strikethrough, and their corresponding html-code is the <del> and <ins> tags. And by most browser, I believe, they are visualised as strikethrough and underlining. Both may of course be changed using CSS. The reason for using .. instead of __ is the possible addition of underlining. (which was my original thought, but I decided against since I'm not that found of underlining).

Note that if you rather like to stick to the traditional markup, it's possible to disable this enhancement by adding $EnableTextEnhance=0 to your config.php-file. Note however, that the old markup is available regardless of what value this variable has.

A second note regarding starting a paragraph with bold text. Using this new markup, you then need to start the paragraph with a space followed by the '**'. This to prevent it from being mistaken as a list element on the second level.

Enjoy...

The deletions and insertions functions in Tavi are very good as they follow what in (x)html (Don't know if other Wikis have the deletions and insertions). (I use Tavi to produce html syntax for blog ;-)) --AaronLaw
