Getting Focus on Radio-Set Element in CHAR (NOT GUI)

[gummbeey]

In Char (NOT GUI), how do you get the focus specfically on a radio-set element?

I need to code the following:

1) If focus is on apple, and user presses "up", focus should go up to v_pet.
2) If focus is on cherry, and user presses "down", focus should go down to v_color.
3) Otherwise, focus should go up/down within the radio-set elements when user presses up/down.

NOTE: Focus does not mean X on the radio-set element.

Thanks,
gummbeey

I'm affraid it looks impossible. The radio-set has low-level triggers on up & down keys. If you define your own triggers they'll become high-level ones and there'll be no possibility to call default low-level triggers from them. Usually this sort of problem happens when you try to define trigger on any key. I think the best idea is to leave it alone.
