In high school, we used Macintoshes. We learned how to use a mouse and copy-paste things in word processors.
There were Macs in college, too. I got quite handy with the fan key and X for cut, C for copy, and so on.
My first job was in a Windows shop. The Control key did the commands.
For almost 20 years, I’ve been using Windows and Control-C for copy, Control-V for paste.
Now, I’m in a Mac shop. It’s fan-C for copy.
I am trying, but I keep hitting the wrong keys.
At least my head hits the desk correctly.
