TTiddlyWiki uses Wiki style markup, a way of lightly "tagging" plain text so it can be transformed into HTML. Edit this Tiddler to see samples.\n\n! Header Samples\n!Header 1\n!!Header 2\n!!!Header 3\n!!!!Header 4\n!!!!!Header 5\n\n! Unordered Lists:\n* Lists are where it's at\n* Just use an asterisk and you're set\n** To nest lists just add more asterisks...\n***...like this\n* The circle makes a great bullet because once you've printed a list you can mark off completed items\n* You can also nest mixed list types\n## Like this\n\n! Ordered Lists\n# Ordered lists are pretty neat too\n# If you're handy with HTML and CSS you could customize the [[numbering scheme|http://www.w3schools.com/css/pr_list-style-type.asp]]\n## To nest, just add more octothorpes (pound signs)...\n### Like this\n* You can also\n** Mix list types\n*** like this\n# Pretty neat don't you think?\n\n! Tiddler links\nTo create a Tiddler link, just use mixed-case WikiWord, or use [[brackets]] for NonWikiWordLinks. This is how the GTD style [[@Action]] lists are created. \n\nNote that existing Tiddlers are in bold and empty Tiddlers are in italics. See CreatingTiddlers for details.\n\n! External Links\nYou can link to [[external sites|http://google.com]] with brackets. You can also LinkToFolders on your machine or network shares.\n\n!

Horizontal Rules\nYou can divide a tiddler into\n----\nsections by typing four dashes on a line by themselves.\n\n!
