Some editors may prefer the wikitext source editor (Wikipedia-style editing). Click the source tab at the top right of the editing window. Some browsers work better with source editing, too. For visual editing click the visual tab.

Rich-text editing (RTE) or "visual editing" can sometimes be problematic, or slow. For example; see Portal: Rich-text editor problems when using Firefox. Visual editing is sometimes called WYSIWYG editing.

To make source editing the default, and to turn off visual editing altogether, logged-in users can change their preference settings. Go to the editing tab in your preferences (Special:Preferences). Uncheck "Enable visual editor," and then save the settings. To turn it back on check the box, and save the settings.
