Mozilla Thunderbird

Make the font larger

Ctrl>

Windows Desktop app Thunderbird on Windows and Linux

Practice this

Press Ctrl + Greater than to make the font larger in Mozilla Thunderbird. It is listed for Windows, and no Mac version is documented here.

Where it works: Writing a message

Ctrl with the full stop also makes the font larger. On a US English keyboard this character needs Shift and the period key. The shortcut itself is unchanged.
