With Content Templater you can create predefined content templates.
Not only can you make complete standard page layouts, you can also use Content Templater for text snippets. So any piece of text you want to use more than once, just make a content template of it!
Under the editor you will get a list of available templates. If you select a template, your predefined content will be pasted in your article or other content item. And all the options you have set in the template will be automatically set (like title, alias, publishing settings, show icons settings, etc.)
