How do I zoom into text with JetBrains IntelliJ IDEA

Solution 1:

I found that you can enable this feature within IntelliJ by opening Preferences(⌘,) > click in the search and then enter the word zoom. Check the box for Change font size (Zoom) with Command+Mouse Wheel.

Now you can hold down the Command and scroll your mouse wheel to zoom in and zoom out.

Solution 2:

You can keymap the usual Cmd +/-/0 in the IntelliJ (or Android Studio) keymap settings by searching for font size in the keymap. Go ahead and set it as shown in the screenshot, and IntelliJ will ask you whether you want to remove it from other assignments.

This works well and it should be the default!
