Additional line breaks when pressing the ENTER key while formatting in the Rich-Text Editor in SharePoint

Symptom

When you use the built-in Rich Text Editor (RTE) to edit content on a SharePoint site, an additional line space is added when pressing the ENTER key. This issue does not occur when you copy and paste multiple lines from a text editor. 
 

Cause

This is expected behavior. By default, the RTE formats paragraph indents and text alignment by using in-line styles. The styles are not consistent among text editors.

For instance:

• When you type any text and press ENTER in RTE, it adds the paragraph tag <p> … </p>.

• When you type any text and press ENTER in Notepad, it adds a <br/> tag.

Resolution

In the SharePoint RTE, use 'SHIFT+ENTER' to add a single line break.

More Information

SharePoint RTE behaves the same way that many HTML editors do. The ENTER key will add a new paragraph (with an additional space).

When you press ENTER in RTE, it adds the paragraph tag <p> … </p>…, which will show as a free line space.
