Zim is a WYSIWYG text editor written in Gtk2-Perl. It aims to bring the concept of a wiki to your desktop. Every page is saved as a text file with wiki markup. Pages can contain links to other pages, and are saved automatically. Zim handles several types of markup, like headings, bullet lists and of course bold, italic and highlighted. This markup is saved as wiki text so you can easily edit it with other editors. Because of the autosave feature you can switch between pages and follow links while editing without worries.
