Desktop or laptop testing: active with cursor

[todd rme]

Is there a way to use a visible mouse cursor in plasma active?  I know
that it is designed to be used with touch devices, but having some way
(perhaps a keyboard shortcut) so desktop and laptop users can at least
boot up the livecd and see what everyone is talking about would be
nice (although it obviously won't give the real experience).  For
people without tablets on-hand, seeing what is possible might
encourage them to get one.
