When trying to save a file that already exists, macOS typically shows the "File already exists, replace it?" popup, like this:

In previous versions of macOS (like Mojave, High Sierra, etc) I was always able to choose either `Cancel` or `Replace` **using the keyboard**.

However since Catalina, it doesn't seem to be working. As displayed in the screenshot above, the `Cancel` button is highlighted by default. If I press the `Return` key it will choose `Cancel`. However I used to be able to switch between `Cancel` and `Replace` by using the `Tab` key. But not anymore.

Also tried the cursor left and right keys (`←` and `→`) but to no avail.

This particular example is from macOS' default Preview app, but it's the same in pretty much any application.

Also in some applications I could previously use something like `⌥`+`Return` or `⌘`+`Return` to choose either the left or right option respectively (`Cancel` or `Replace` in this case) but that doesn't seem to be working either.

Is there a different keyboard shortcut or combination of buttons nowadays? Or do I really HAVE to use the mouse to choose `Replace` ?
