How do I make the incoming messages smaller? I can't find a place in tools settings for that? Thank you.

Thank you for helping me with changing the font, etc. on messages. How do I make the incoming messages smaller? I can’t find a place in tools settings for that? Thank you.

Highlight the message in the message pane and press [ctrl]+ to enlarge and [ctrl]- to shrink.  If your mouse has a scroll wheel, you can also highlight the message in the message pane, hold down the [ctrl] key and scroll the wheel.
