Hi, I am currently using a Logitech Windows Keyboard with my Imac (the wireless keyboard / trackpad are being used in my room for my macbook + external monitor setup, where I felt the lack of wires would be better served (and I don't want to buy another Apple keyboard). It's working great, but I can't figure out how to get the ALT key to be recognised as CMD. I use it extensively when adjusting screen sizes in Safari. I went to Preferences - Keyboard - Modifier keys but I cannot find the ALT option anywhere. Currently using CTRL as CMD, but that means that copy and paste and screenshotting is awkward all over again, and my ALT key is still useless. I tried searching online, but couldn't find any help. It's probably something very simple that I am overlooking, so your assistance would be much appreciated. Thanks in advance.
