Clicking a toolbar icon lets you perform the following on selected text:
bold/italics
link inside/outside our wiki
level 2 headline; add picture
mask wiki text; add separator
Markup
By using just the toolbar, you can write a whole wiki page. However, feel free to start learning wiki markup: If text is preceded and/or followed by a set of characters, they tell the text how to behave. Examples:
What you want
What you type
What you get
Bold text
An '''example''' of bold text.
An example of bold text.
Green text
An <font color="green">example</font> of green text.
