Hi
I am working on a virtual environment (parallels) on a mac and did struggle a lot activating the CTRL + SHIFT option to resize and move object within a chart (the red boxes). Creating alternative combinations did not do the job form me. after clicking CTRL _SHIFT in a chart I did see the boxes but when I clicked on the mouse to move or resize I did get the properties box. I just discovered that also selecting on the CMD key the properties menu does not appear and the objects can be moved and resized as desired
good luck working on your mac !
