Love it when applications respect platform conventions. I had a Fantastical alert with 12 replies that I had to click OK on… and then I thought… if Command-W is Close window, and Command-Option-W is Close all windows… and that works also by Option-clicking the close button of a window… maybe Option-clicking OK will do the trick?
Sure enough, as soon as I pressed the Option key, the button changed to OK to all. Thanks, @flexibits!
