Okay, I'm kind of strange. I love my Ctrl+ command. Do you know why?
A couple of weeks ago I switched from Internet Explorer 8 to Firefox 4. IE had a button to enlarge the text in my browser. Forefix does not.
So I've had to start hitting Ctrl and + to make my browser larger.
Making my browser larger has been more important because screen resolutions keep getting higher and my eyesight keeps getting worse.
That's why I love Ctrl+.
