For a LaTeX Beamer quote, traditional English quotation-mark entry requires that double outer marks be used for US English and single outer marks for UK English. This rule reverses itself for nested quotations. For text-mode double quotes, use two opening backticks and two closing apostrophes. For text-mode single quotes, use one opening backtick and one closing apostrophe.
``…''
`…'
In US English, “…” is outside; in UK English, ‘…’ is outside.
