Hence, many of these sites offer some means to edit the wikitext directly.
However, WYSIWYG controls do not always provide all of the features available in wikitext, and some users prefer not to use a WYSIWYG editor.
Wikis can make WYSIWYG editing available to users, usually by means of JavaScript control that translates graphically entered formatting instructions into the corresponding HTML tags or wikitext.
