P: Shortcut for "Grid Snap: Off"

I create photo books with lots of text and photos. To align text and photos I most of the time have “Grid Snap” set to “Cells”. But sometimes there is a need to place something a bit beside an already existing frame and then one has to set “Grid Snap” to “Off” and when done set it back to “Cells”.

What I would like to see is something like press “Shift” while using cursor to move the cell in question. The “Shift + “Cell move” set the “Grid Snap” temporarily to “Off”. When the move is done and “Shift” is released the “Grid Snap” is returned to “Cells".

This functionality would improve the workflow a lot in the Book module.
