You can create bulleted and numbered lists in a quite natural way. All you do is inserting the line containing the list item. To get bulleted items, start the item with an asterisk "*"; to get numbered items, start it with a number template "1.", "a.", "A.", "i." or "I.". Anything else will just indent the line. To start a numbered list with a certain initial value, append "#value" to the number template.
To nest lists of different levels, you use different depths of indenting. All items on the same indent level belong to the same (sub-)list. That also means that you cannot change the style of a list after you started it.
Definition lists can be created by items of the form <whitespace>term:: definition; note that the term cannot currently contain any wiki markup.
