On Windows, you might use PuTTY as a terminal,

or use cmd or PowerShell on Windows itself. One problem that can arise is that when you enter docker ps,

if you have a lot of projects open and their names are long, the lines wrap, making the output difficult to read.

To solve this problem, you need to adjust the terminal's font size.

The problem is that on a Mac, you adjust the font size by pressing the cmd + - keys.

Wow~~~ Why are there so many things on a Mac that require keyboard shortcuts...

So I looked for a way to change this to ctrl + mouse scrolling, but couldn't find anywhere that supported it.

So I installed an application called BetterTouchTool.

This application is used by more Mac users than you might expect.

First, since changing the font size also changes the terminal window size, you need to disable that by

turning off the relevant option in the iTerm2 settings.

Now you need to configure the BTT app.

It's very simple: select the iTerm2 app, then set the key mapping for the cmd + scroll up event in that app to cmd + so that the key command is executed.

With this setup, scrolling the mouse in iTerm2 changes the font size.
