Hang on. What you're saying is that I enter a new value size value in
the Selector InfoBar, for example, press Return and *nothing* should
happen.

That's not going to work is it.

Yes I agree that's a good idea. Additionally it helps users know which
dialogs are dockable and which are not.

Well Phil's rules say that once it's done it's job it hand focus back
and so clicking and dragging a window could be regarded as completing
it's job (being moved), so it should hand focus back afterwards.

I can't see why it's an issue even for dialogs that do not have editable
fields. Why would you want to give it focus even, or rather why would
you want Alt-F4 to close the window ever (if it doesn't have focus, it
hardly makes sense to first click on it and then press Alt-F4, when you
could just click directly on the close box. Return would have no purpose
because there's nothing to commit. Esc ditto - it would have no meaning
on a dialog that has not had any edit just done to it (there's no
operation pending to cancel).

Oh yes close Windows short cuts are useful and standard. So that Alt-F4
should close the dialog, irrespective of whether it's modal or modeless.

Don't understand that. Return does the commit. See above.
