Enable Hotkeys in ALV Toolbar buttons

Hello all..

As you know we can use Hotkeys for Toolbar buttons as described in the below link: http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/b951297a6d2d65e10000000a42189c/frameset.htm

I am not able to see any option in class for ALV Button in the Toolbar. So I just want to know that is there a work-around for enabling Hot-Keys for ALV-Buttons?

Thanks,

Sanket Sethi
