Help:WikiText editor - Edit toolbar

In compatible browsers, an edit toolbar can be automatically displayed with the edit box, provided that this has been set in the preferences. It appears automatically for editors who are not logged in. This functions partly as a typing aid and partly as a reminder of the available functions. All the functions are available simply by using wikitext conventions and typing the code directly into the edit box (such as [[link]] ). If you do much editing you may find that you get comfortable with wikitext for many things, but still rely on the toolbar when you can't recall the syntax, need special characters, or to insert a figure. The toolbar works with Internet Explorer, the Mozilla Suite/SeaMonkey, Firefox, Konqueror, Safari, Opera and Google Chrome.

In Mozilla browsers, IE, and Chrome you can format existing text by highlighting the text you want to format and clicking the relevant button on the toolbar. If you click a button without selecting any text, sample text will be inserted at the cursor's position (like so: Bold text). In other browsers, clicking on the button presents an explanation for that feature. (Pre-release 9.0 versions of Opera browser also seem to support the advanced functionality.)
