KDE Virtual Desktops: hotkeyable ?

I am playing with KDE a bit, I am used to windowmaker. Is it possible to
assign a hotkey to each virtual desktop? I want to make it like
windowmaker alt 1-9 to switch to the different ones rather than having
to click on something or hit alt-tab constantly.

thanks.
