WYSIWYG stands for “what you see is what you get”. In computing, a WYSIWYG editor allows users to edit content in a form closely resembling its end result. The first WYSIWYG editor was a word processing program called Bravo and invented by Charles Simonyi at the Xerox Palo Alto Research Center in the 1970s. It became the basis for WYSIWYG applications like Word and Excel. ClickHelp is also a WYSIWYG application, so technical writers can easily write documentation and visualize what they will get.
