I'm working on it too.
Skids- Cycle faster than you think you should, lock a leg - which'll push you off the seat and forward (unweighting the back wheel)
Then when feet are about level- pull up with the front foot and down with the back (ie opposite to cycling)- and you'll skid- or skip- probably.
Its worked for me.
Oh and humping the handlebar helps.
That was thanks to Sheldon Brown's page- also look at http://www.63xc.com.
