increase/decrease Clip Gain by keycommand (external controller)

I come from a Nuendo background and there we had the option to increase/decrease the clip gain by +/- 1 dB with a keycommand (or with a Hardware controller).

we have the "clip gain" command but that only brings up the clip preferences up and puts the cursor at the numeric value.. so, still al lot mouse or numeric keypad hassle for a simple level adjustment..
