When you ctrl+ left-Click, it’s like a right-click in Mac OS X and brings up a menu.
I’m trying to clone a selected rectangle as shown here
But if I ctrl+alt+ click, I just get a context menu because Mac OS X is thinking I’m right-clicking.
How do I do this? I know I can copy/paste/move. But I want the shortcut method.
Answer
Command+Option+ click on the Mac
Windows Ctrl = Mac Command (Apple key)
Windows Alt = Mac Option
