Option "XkbOptions" "grp:ctrl_shift_toggle,lv3:win_switch"
Or something like this... I don't use it myself. But you need to edit the options to allow the switch from the keyboard. xf86config should allow you to define this without having to guess exactly what options you need.
EDIT: That line should be in /etc/X11/XF86Config... but unless you know what you are doing you want to use the utility. Remember to restart X for it to take effect.
