When sailing with crew I do as AdamLein suggest and lift the tiller handle, move to other side and lower tiller handle back down.
When sailing alone I use three bungee cords wrapping one bungee around the tiller once and attaching one to each side from the tiller to the stern rail. This allows me to set the tiller and stand beside it. When ready to tack I have a sheet in each hand and just lean into the tiller to turn adjusting sheets accordingly.
The bungees also work as a cheap tiller tender allowing me to move around freely once course is set.
A people that values its privileges above it's principles will soon lose both.
