I had been thinking the same.  Left & right could active the
first arrow pair on all the dialogs.

If joypad has multiple buttons, different buttons can be mapped to:
- activate focused item
- select default item
- select cancel item

I think those arrow items need specific flags & activation for
them (= search for that flag).  This would allow mapping
both joy left & right and left & right arrow keys to them.

I guess I need to move shortcuts from flags to state [1], to make
space for the extra flag bits.

[1] Especially as I had changed shorcuts to be parsed at run-time
    from the text labels, so they're now state (run-time modified).
    This will allow shortcuts to be specified in translations
    loaded at run-time.  Handling of accented letters as shortcuts
    will be an issue with SDL2 if those letters don't have their
    own keys though...

It's probably better make the navigation work the same in every
dialog (-> less code & documentation needed and more discoverable).

I would actually like to have separate AltGr shortcut for each
joystick (AltGr 0, AltGr 1 etc), which would switch given joystick
between disabled, keyboard and real joystick.  Would that cause
any problems?  Or is there some other, more deserving config
change you think should be bound to AltGr+<number>?

I got already used to not needing modifier, but modifier would
be more familiar to users and would indeed solve this issue.
I'll look into that, but I'm not sure when I'll have time to
do it.
