The Copy Formatting feature is provided through the optional Copy Formatting plugin. It was introduced in CKEditor 4.6 and by default is available in the Full distribution only.
When the plugin is enabled, thebutton is automatically added to the editor toolbar. You can use it to copy text formatting from one place in the document and apply it to another. This helps easily preserve stylistic consistency of the document.
To copy styles, place your cursor inside the text (or select a styled document fragment) and press thebutton or use the Ctrl+Shift+C keyboard shortcut. Then place the cursor inside some word or select a part of the text to apply formatting to it. The copied formatting can also be applied by using the Ctrl+Shift+V keyboard shortcut.
Note that not all styles can be copied or removed. For example, Copy Formatting will not copy styles from links and will not remove links when you apply formatting to them. The default filter can be adjusted, though — see the example with filter customization below.
Copy Formatting only works with inline styles, so it will not copy or apply block-level styles (e.g. headers) to text.
A special sticky mode allows you to copy formatting once and apply it in more than one place. To enable it, double-click thebutton or use the Ctrl+Shift+C keyboard shortcut. The sticky mode can be switched off by clicking the button again or by pressing the Esc key.
It is also possible to copy formatting in tables and lists, including in some complex scenarios like nested lists or tables. In case of lists, it is even able to change the list type or start value, so applying formatting from a bulleted list to a numbered one will effectively change the list type from numbered to bulleted.
Formatting from certain type of elements cannot be copied. By default these elements include links, headings, images, iframes, widgets and media embeds.
This can be changed through two configuration options available:
As an example, you are only allowed to copy bold formatting in the editor below.
Additionally, you can also limit the contexts (style types) that are enabled for the Copy Formatting feature from the default plain text, list and table styles. The example below uses the
config.copyFormatting_allowedContexts configuration option set to
'text' to only enable copying of text styles (specifically, as set above, just bold), so e.g. table styles will not work.
A few configuration options are available to fine-tune the Copy Formatting feature, including adjusting the default keyboard shortcuts or turning off the special "disabled" cursor that indicates you cannot apply the formatting copied from the editor content outside the editor.
