MacOS – How to make the cursor return to its normal size

Apparently because of either some BetterTouchTool shortcut or bug¹ I have a gigantic mouse cursor, and I can't reverse it. BetterTouchTool has the option to toggle the cursor size, but instead of going back and forth between normal and larger, it just gets larger and larger and larger. This is driving me crazy and can only be fixed by rebooting, as far as I know.

I need some way of restoring the mouse cursor to its original dimensions. How can I do this?

¹ In the past I used BTT's ability to toggle mouse cursor size to visually signal that my shortcuts were working. But now something is doing that without my knowledge or consent.

I've searched through all of my BetterTouchTool shortcuts and I can't find one causing the problem, so it may be a bug in the software itself, or it may be a result of a combination of lacking a good enough search engine and me somehow overlooking it.
