In dialog boxes, pressing the tab key should only navigate between text fields. It used to do this. Now it navigates through every field, button and popup menu. There is a system keyboard setting that regulates this. InDesign now ignores this setting.

For example, in the New Document box, press the tab key repeatedly and it goes:

Facing Pages > Start Page # > Primary Text Frame > Page Size > Width ...and so on.

It should only go:

Start Page # > Width ...all those other buttons etc should be skipped.
