You’ll notice that when I go over the parentheses the one I’ve selected and it’s pair turn yellow, unless there isn’t a pair of course. You can also use Ctrl-] to flip between the open and close parenthesis in a pair. This can be particularly useful to make sure that you remembered a close parenthesis at the end of a subquery. In this case that last close parenthesis doesn’t have a match. Now finding out that you are missing an open parenthesis doesn’t mean you know where it’s supposed to go. But you can track the different pairs, making sure that each time you open a parenthesis you close it in the correct place. In this case it belonged right at the beginning.
FYI yellow isn’t the default (it’s a light gray). I find the default hard to see (I’m getting old) so I changed it to yellow in the options under fonts and colors.
