Method of drag selecting rather than selecting each individual entity
Hi,
I was wondering if there is anyway of drag (area) selecting entities in gmsh? For example when deleting elements, I have to select each element by clicking on them individually, (or by volume etc...) but if I wanted to only delete a large section of elements then drag selecting on the screen would be very useful. If it is not currently available, but can be activated in the source code somewhere, any advice on how to do this would also be appreciated.
Many thanks
