I've had another look at this Martin and sure enough it can be done.

Assuming the two "closed" objects are selected, the sequence of events
is as follows:

CTRL-I
CTRL-K
ALT-drag the original and clone to select both (note - there is
nothing to indicate the shapes are selected and if you get this bit
wrong and end up selecting only the clone the rest of the procedure
fails).
CTRL-W
CTRL-L
Select intersection and delete.

Six steps are needed. Could this be simplified in the future. The
abitity to join multiple shapes in a simplified way might allow some
interesting geometric patterns to be created.

The other reason is that in 3 months time I will have forgotten how to
do this and have to refer to the tutorial again.

Best regards

Richard
