Yes. Copy with cite is available for cases, statutes, and secondary sources. You can also choose between California Style Manual and "Standard," or Blue Book style, for your citations.
Note that for the citation to copy with the highlighted text, you must click “Copy” above your selected style. Using a keyboard shortcut to copy the text will only include the text, and not the citation. Pasting the properly copied text with citation, however, can be completed with a keyboard shortcut.
