VisualEditor is a way to edit pages that looks more like a word processor. It was first offered here in 2013.
How do I enable VisualEditor?
VisualEditor is available alongside the original wikitext editor if you opt-in, by changing your preferences. It is currently not available to unregistered users at the English Wikipedia, unless they switch modes while editing.
Why is this change being made?
Some people who could become productive, experienced members of the community are turned off upon attempting their first edit in wikitext "source" mode. Some edits, such as adding or rearranging columns to a table in wikitext, are difficult even for experienced editors.
Where do I go to learn more about how to use VisualEditor?
In most cases, VisualEditor will not change or reformat lines that are not being directly edited. If markup already on the page is handled incorrectly (for example, with tables that are not closed), then it may attempt to correct these.
Will it still be possible to edit articles using wikitext after the visual editor becomes available?
Yes. While the visual editor will become available to all users as an editing environment, a method for editing the underlying wikitext "source" will continue to exist. There are no plans to remove the "Edit source" option.
Won't this slow down reading and editing for people who have slow connections or computers?
I've found an issue with VisualEditor or a feature that is missing. How can I tell you to fix it?
Something breaks: The failure may only affect a particular type of browser or computer, on a particular page, or after doing something else. Please post your problem at Wikipedia:VisualEditor/Feedback. In your description, it is helpful to include information about what you were trying to do, your web browser, computer operating system, and a link to the article or a diff of the edit if it was possible for you to save the change.
Performance problems: If all pages seem unexpectedly slow on loading or on performing a particular task, or if it used to be faster and has recently gotten worse, then please report this.
User experience issues: If it didn't make sense, or if it was awkward, or if you couldn't figure out what you needed to do (Wikipedia:VisualEditor/User guide covers the basics), please speak up, and feel free to offer your suggestions for improving the design.
Missing functionality: Is there something you need to do, but it currently can't be done in VisualEditor, like editing mathematics equations or seeing hidden comments that contain instructions to other editors? Make sure that it's on the developers' list of needed features. If you'd like to know which missing features have been reported before, you can search the talk page archives and feedback archives. If you can't find any reference to the new feature you'd like to suggest, please report it at mw:VisualEditor/Feedback.
To continue to edit the wikitext directly, simply click the "Edit source" button instead of "Edit". On section edit links, you can open the wikitext editor selected in your preferences for that section by clicking "edit source" instead of the regular "edit" link.
If you would like to remove VisualEditor from the user interface, then you can do so.
If it is a beta feature: go to the Beta tab of your preferences page, untick the checkbox "Visual Editor", and click the Save button near the bottom of the page. (As of 2021, this is how you do it on Meta-Wiki and the Chinese Wikipedia.)
If the visual editor is already out of beta:
go to the Editing tab of your Preferences page, untick the checkbox "Temporarily disable the visual editor while it is in beta", and click the Save button near the bottom of the page. (This is how you do it on some sister Wikipedias, for instance, Russian Wikipedia, as of 2021.)
^<<And no, we're not taking markup-level editing away. Some users may always prefer it over visual editing, even if the exact nature of the markup changes, and even if VisualEditor becomes the best tool it can possibly be.>> Erik Möller, deputy director of the Wikimedia Foundation, The VisualEditor Beta and the path to change, op-ed for Wikipedia Signpost, July 31st, 2013.
