Adding Curly Brackets for Multiple Lines of Text in Pages

Only by using the equation editor and the following syntax where the text entries can be single lines of text. The curly brace will grow vertically to match the individually added lines of text. The \\ operator is LaTeX speak for newline.

\begin{cases}

First \\
Second \\
Third \\
Fourth

\end{cases}

Tested: Pages v13.2 with Sonoma 14.0.

If done in MacTeX 2023, one can add LaTeX packages that allow one to use any font on the Mac they choose for the bracketed text. The Equation editor in Pages does not have this feature.

Just an addendum to this. It does not like sentences or strings of words as it will concatenate the letters omitting any word spacing. The following fixes the space elimination of long sentences in the block:

\begin{cases}

\text{As any dedicated reader can clearly see} \\
cat \\
dog \\
wolf \\
firefly

\end{cases}
