Preferences | Customize | Keys default active control

When Customize preferences are open with command "Prefs CUSTOMIZE=keys" or just with Keys page active from the previous session, the active control is button OK.
Is it possible to make the behaviour like in Preferences page with Filter as the default active control. Very often that would save an extra click. An extra option/argument in the Prefs command would be more than enough for me.

Thanks,
Alex
