Unlearn to relearn

After three weeks of using a PC at work (my staff iMac was in a computer hospital), I'm now struggling to get back into Apple keystrokes at home.

I'd become used to strange menus appearing every time I hit the wrong keys as I retrained my fingers for a Dell keyboard.

Now I'm working at home on my Mac desktop, I'm trying to unlearn in order to relearn!

And who's bright idea was it to shift the f#<*ing speech marks and 'at' symbol around?
