xboard: ICS interaction: i need a tab that navigate in main console window

If i want to see the main window (from ICS Interaction) i have to press 
Alt Tab to set board focus then i have to type some character to have 
back main ICS Interaction window, while to simply press tab would be 
very useful to navigate trough friends, channels or main window.
This would set free mouse to play on board (very useful for blitz or 
lightning games where moving mouse from board is a waste of precious msec).

Im using arch linux xboard
Thanks you very much for xboard/winboard

ciao!
