I use Wolfram on my MacBook Pro, which is implemented with Windows 10 system. Since the MacBook laptop does not have the “Alt” button, I was stuck when I go through when I want to get coordinations of opposite corners of a rectangle on map, drawn by Get Coordinates Tool in Drawing Palette. I have tried pressing the "option" button as the alternative for "alt", and then follow the “drag” instruction, but the rectangle still did not show. Is there any way to overcome this problem?
