The only code MediaWiki:Common.js/edit.js contains is the Extra edit buttons script (XEB) (a small additional piece of support is found in MediaWiki:Live.css). XEB was written by MarkS of Wikipedia, and it is used on OniGalore to add buttons to the toolbar for all editors. However, by reading the documentation below, you can take things a step further and use XEB to customize the toolbar as it appears for only you. You can:

  • Re-order the existing buttons.
  • Add buttons to the toolbar from the pre-defined list below.
  • Define new buttons, and even attach pop-up dialogs to them.

Re-ordering the buttons

XEB parses a string variable called XEBOrder to know which buttons to place in the toolbar in which order. If there is no string passed in to set XEBOrder, it uses its own hardcoded value in order to provide a default editing toolbar. To set this variable and get your own custom toolbar, you use a custom JavaScript page under your user name, such as User:YourName/monobook.js or User:YourName/vector.js.

First, look at the edit.js page with XEB's code -- find the initButtons() function, and you'll see the default button order (actually called XEBOrder2):


Let's say that you wanted to move the "Insert signature" button from the right to the left side of the toolbar. Looking at the table on the right, you can see that the signature button has the ID "9", so you would add this text to your custom JS page: XEBOrder="9,0,1,U,F,D,C,D1,4,A,2,3,E,G,8,H"; importScript('MediaWiki:Common.js/edit.js');

Notice that the "9" comes first now. You will not see the "Insert signature" button move up in the actual toolbar, however, until your cache is cleared. Note that you will have to be on a wiki page in editing mode before trying this if you want to see the change take effect before your eyes.

Adding buttons

As you can see on the right, there's lots more choices available than what the default toolbar provides. For instance, here's my custom toolbar code:

if (wgAction == "edit" || wgAction == "submit" || wgPageName == "Special:Upload")



You might be wondering why I have a commented-out line that sets myButtons. What's that for?

Defining new buttons

XEB can also work with extra buttons created by the user. To do this you must define the myButtons variable on your custom JS page. The format of myButtons is:



  • CODE is a code for the button. You should place this code in XEBOrder to make your button appear on the toolbar. You can use any text you like. However, it is recommended that you start the code with an underscore to make sure it doesn't clash with any future standard XEB buttons. This must be in upper case letters.
  • url is the full URL to the button image. You must enter the URL of the image on its own, rather than the Wikimedia page that describes the button, so use: "" rather than "" (incidentally, you can use that image as the base for a new button icon).
  • Tooltip is the pop-up tooltip that will appear when the mouse moves over the button.
  • Before is the text to insert before the current cursor location.
  • After is the text to place after the current cursor location.
  • Text is the text that is placed between Before and After. If the user has selected text in the edit box, when the button is pressed this selected text will be placed between Before and After instead of Text.

This example defines two extra buttons:

'Mark Test','Before','After','Middle'],'_ZA':'
Button_enter.png','Mark2 Test','111','333','222']};

For more examples and usable buttons, see the !voting/discussion buttons made by Willscrlt of Wikipedia.

Special button instructions

Reference Buttons

The buttons for placing a reference come in two flavors:

  1. Button 'R' adds basic reference tags to some selected text.
  2. Button 'R1' calls up a dialog to create a named reference (names are used for referring more than once to the same source citation).

'R2' is used for placing the footer at the bottom of an article that lists all the footnotes based on the article's ref tags.

Smart Table Wizard

Allows the user to set:

  • Number of rows
  • Number of columns
  • If the table is sortable
  • Whether or not a title row is required.

Advanced Image

Allows the user to set:

  • Image size
  • Image location
  • Image caption
  • Image URL

BSL Template Wizards

Allow the user to insert calls to the BSLfuncinfo and BSLvarinfo templates, used for listing functions and variables in the BSL documentation.
