1182 // * Buttons with "Cancel" title will be displayed as the last buttons in the modal
1183 // * Last button added to the modal via `addButtonWithTitle` stays focused
1184 // * Focused buttons react on "space"/" " keypresses
1185 // * Usage of `keyEquivalent`, `makeFirstResponder` or `setInitialFirstResponder` does not change the focus
1186 //
1187 // See also https://developer.apple.com/documentation/appkit/nsalert/1524532-addbuttonwithtitle#discussion
1188 // ```
1189 // By default, the first button has a key equivalent of Return,
1190 // any button with a title of “Cancel” has a key equivalent of Escape,
1191 // and any button with the title “Don’t Save” has a key equivalent of Command-D (but only if it’s not the first button).
1192 // ```

1194 // To avoid situations when the last element added is "Cancel" and it gets the focus
1195 // (hence stealing both ESC and Space shortcuts), we find and add one non-Cancel button
1196 // last, so it gets focus and a Space shortcut.
1197 // This way, "Save this file? Yes/No/Cancel"-ish modals will get all three buttons mapped with a key.
