Scalar Notes
A Scalar note allows you to add annotations to your text. Scalar notes can be composed of text or media, allowing you to comment on or illustrate ideas. Scalar notes can also be a good way to provide definitions or translations to foreign language terms or add citations.
Scalar notes are similar to media in that you can tie notes to specific pieces of text or place them precisely in a specific location on the page. To create a note that appears as a pop up, select a portion of the text and click the Scalar note button 
Inline scalar notes will appear in boxes embedded on your page. These can be a great way to feature a primary text/quote, short biography, or complementary text.

You can also add annotations to images, videos, audio. For images, annotations will appear in the form of transparent boxes when you roll over the image area with your mouse. Clicking on the annotation area will display a pop up window over the image.
Annotations can be made to a chosen image by choosing an object and clicking the paperclip icon in the top right hand corner. Click and drag to draw a box around the area you’d like to annotate and enter a title. You can then add additional text and tags by selecting your annotation in the table below.
You can find your annotations in the content menu, listed by title. If you click to edit that annotation, you’ll be able to freely mix text and media, just as you would when crafting a page. This means that you can annotate an image with anything, including other images and videos.
Lastly, you can control whether or not annotations will appear when you add media items to your page. If your selected media has annotations, you’ll be asked to select which, if any, you would like to appear on your live page.

You can add as many annotations as you like to any media item. Just as with images, you can select which, if any, annotations you would like to appear on a given page. You can also set a video or audio file to skip to one of the annotations by selecting a “Featured Annotation” while Media Formatting Options.
