Page Navigation Using the “Tab” Key
To ease page navigation by using keyboard and further boost accessibility, CKEditor can be reached by using the Tab and Shift+Tab shortcuts that are commonly used for navigating between page elements.
This is a default behavior that works for both classic and inline editors. For classic,
iframe-based editors, you will simply enter the editing area. For inline editors, the toolbar will appear for each editable element that you navigate to and editing it will become enabled.
# Influencing Tab Index
You can customize the place that CKEditor will take in the Tab order of a web page that it is embedded in. Use the CKEDITOR.config.tabIndex option to assign a custom
tabindex value to a CKEditor instance. For example:
config.tabIndex = 3;
This will cause CKEditor to become the third page element that you will enter when using the Tab key, no matter what its position could be in the page source.
Please note that this configuration setting is an equivalent of adding the standard
tabindex attribute to the element that is being replaced with CKEditor.
