PanelVie Plus object focus change by arrow keys

Hello!

Just one question to make sure I understand correctly.
Is it possible at all to navigate between different objects (making them on focus) by using arrows instead of TAB key? The main issue is that I have a lot of objects on screen and it would be nice if customer can move cursor also upwards and downwards.

PS
The customer does not like the idea of using mouse.

Nope. Tab is the only way to move selection between objects on a PanelView Plus when you don't have a mouse.
