'Intellij: What does the green box around my source mean? How can I disable it?

I enabled a setting by mistake in IntelliJ giving me a green outline around parts of my source:

Green outline IntelliJ

What does this outline mean and how can I disable it again?

I'm seeing this happen when it is highlighting the current scope of an item. It seems to happen when you hold down control and right click on a bit of code, but it probably depends on your keymappings. (I'm using default GNOME keymappings)

Escape seems to clear it.
