Extend "Select Cells On" etc. to the missing boolean operations.
Currently the menu options: Select Cells On, Select Cells Through, Select Points On/Through ... offer the possibility to select subsets with the mouse. An already selected "selection" can be extended with the Ctrl key as modifier and the same commands. But it is not possible to remove from the selection with for example the Alt key as modifier (as is implemented in a lot of other programs). This would be a conventient extension of these 4 menu commands.
