Configure the Wikitext field to link to other sources within the system.

## Before you begin

Role required: personalize_dictionary

## Procedure

1. Right-click in the header of the new Wikitext field.
2. Select Configure Dictionary
3. In the Dependent field of the dictionary form, enter the field you want to use for linking to other pages.  
   For example, on the Incident table, you might choose the
   number field.  

   This configuration enables you to link to any incident by using that
   incident's number. For example, to open INC0000002, you enter
   <kbd class="ph userinput">[[INC0000002]]</kbd>.  
   The following [dictionary attributes](https://servicenow-prod.fluidtopics.net/W62P_HvztvVqWYI5duwoKQ "Dictionary attributes alter the behavior of the table or field that the dictionary record describes. Administrators can add or modify dictionary attributes.") are available for wiki_text fields.
   * preview_first=true - sets the preview mode to display on page load, otherwise editor will be displayed
   * preview_selector=true - enables the toggle button to switch between the editor and preview
   * dual_mode=true - enables displaying both the editor and the preview simultaneously during edit mode.
