Help:Show preview

Below the edit box is a Show preview button. Pressing this will show you what the article will look like without actually saving it. It is strongly recommended that you use this before saving.

The "show preview" button is right next to the "save page" button and below the edit summary field.

Editing[edit]

Use preview during editing to check what the page will look like after saving and to check that you haven't made any errors. It also prevents the need for multiple saves. Saving the same article several times in quick succession makes it harder for people to check what changed, and clogs up the page history. When making major edits, consider copying the content into your clipboard. The Wikipedia servers sometimes have hiccups, and you could lose your work.

Tip: When you preview, you will also see a preview of the edit summary, so e.g. links can be checked.

Live preview[edit]

You can get a live preview, also known as Quick-preview or AJAX preview, whereby only the preview area will reload, as opposed to the entire page. You can enable this option in your Preferences, by selecting the option Use live preview in the Editing section.

There are also several user scripts that provide similar or additional functionality, such as:

  • wikEd, a large JavaScript based editor with lots of features.
  • User:Js/ajaxPreview, adds a preview button above the edit textarea.

Other advantages[edit]

Using Show preview prevents your login timing out, which would mean your edits would not be attributed to your user name. Clicking preview regularly will restart the timer, so you remain logged in. Also, if you are no longer logged in, showing a preview will make you aware of this so you can log in and save your work after that. You can check this by seeing if your user name appears in the upper-right corner when you press preview. If you are not logged in, open Special:Userlogin in a separate window (right-click "Log in" and hit "Open link in new window" or similar). Log in, then go back to your editing and hit "preview" again to make sure all is well. Note that this will clear the minor edit and watch checkboxes, so make sure they're set appropriately again before you finally save the page.

Templates[edit]

Typically, the noinclude-part of a template page contains examples including or substituting the template. Changes in the working of the template (i.e. changes outside the noinclude-part) are not yet effective in these examples in preview and, in the case of substitution, in "show changes".
