In High Sierra, with a mouse, whenever I right click something that doesn't have a specific "right click behavior", the right click is treated as a left click.
For example, if I right click text in an IDE, it will correctly display a menu to, say, copy/paste that text. However, if I right click one of the options in that menu, that option will be selected as if I had done a left click. This happens in every app
Can this be disabled somehow? Is it different in Mojave?
