+
+!Hyperlinks
+* [[WikiWords|WikiWord]] are automatically transformed to hyperlinks to the respective tiddler
+** the automatic transformation can be suppressed by preceding the respective WikiWord with a tilde ({{{~}}}): {{{~WikiWord}}}
+* [[PrettyLinks]] are enclosed in square brackets and contain the desired tiddler name: {{{[[tiddler name]]}}}
+** optionally, a custom title or description can be added, separated by a pipe character ({{{|}}}): {{{[[title|target]]}}}<br>'''N.B.:''' In this case, the target can also be any website (i.e. URL).
+
+!Custom Styling
+* {{{@@CssProperty:value;CssProperty:value;...@@}}}<br>''N.B.:'' CSS color definitions should use lowercase letters to prevent the inadvertent creation of WikiWords.
+* <html><code>{{customCssClass{...}}}</code></html>
+* raw HTML can be inserted by enclosing the respective code in HTML tags: {{{<html> ... </html>}}}
+
+!Special Markers
+* {{{<br>}}} forces a manual line break
+* {{{----}}} creates a horizontal ruler
+* [[HTML entities|http://www.tiddlywiki.com/#HtmlEntities]]
+* [[HTML entities local|HtmlEntities]]
+* {{{<<macroName>>}}} calls the respective [[macro|Macros]]
+* To hide text within a tiddler so that it is not displayed, it can be wrapped in {{{/%}}} and {{{%/}}}.<br/>This can be a useful trick for hiding drafts or annotating complex markup.
+* To prevent wiki markup from taking effect for a particular section, that section can be enclosed in three double quotes: e.g. {{{"""WikiWord"""}}}.
