When creating a new reference in Endnote online, every field opens as a WYSIWYG-frame. As a consequence, text that is copied from a formatted source, such as web page or PDF, keeps most of the formatting. If you do *not* want the format (color, typeface, bold, text size, …) you have to work around by copy/pasting/copy-ing it in for example a plain text editor such as Notepad in windows.
An option to ‘paste without format’ or a button to remove formatting would be a real convenience.
