Clicking on a blank space at the top edge of the grid will select/deselect heads in the whole column depending on the current
selection state of the heads.
Clicking on a blank space on the left edge of the grid will select/deselect heads in the whole row depending on the current
selection state of the heads.
Clicking on a blank space at the bottom edge of the grid will select the whole column regardless of the current state of selection
of the heads.
Clicking on a blank space at the right edge of the grid will deselect the whole row regardless of the current state of selection of
the heads.
Clicking within the grid on a blank space that is adjacent to a head will have the same effect as above – but only for all the heads
directly adjacent to each other. As it is possible that the blank space that is clicked on may have more than one adjacent head, the
priority is left, top, right, bottom.
For other plans where head numbers are packed into the grid with no blank spaces – e.g. LED arrays, it is still possible to use
this method but the grid must have blank spaces around the edges of the grid.
