[Paraview] "Select Cells On" etc.: Remove current selection from whole selection - possible?

[Prof. Dr. Karl-Heinz Kunzelmann]

Hello to everybody,

my question today relates to the useful GUI tools "Select Points/Cells 
On/Trough". I already found out that I can extend an excisting selection 
with the Ctrl-key. But I could not find something to remove a small part 
from the selection with but keep most of the selected points/cells.

In other programs (ie. ImageJ/Fiji) they use the ALT key to remove the 
current selection from the total selection but keep the rest (usually 
the boolean combinations are supported). I would assume that this is 
could be already possible with Paraview as well and I just cannot find it.

If it is not supported. Would it be a big effort to implement this feature?

Sincerely

Karl-Heinz
