it's the little things
John Gruber over at Daring Fireball posted a short bit a while back about the Japanese concept of poka-yoke.
A fine example of this concept is illustrated in the differences between version 2 and the beta of version 3 of Apple's web browser, Safari. To make sense of the following screenshots, you also need to know that the keyboard shortcut to enter URLs is Command-L, and use a QWERTY-style keyboard.
The old version of Safari's shortcut to block pop-up windows was right next to the key sequence to move focus to the address bar. This would occasionally lead to inadvertent toggles of the pop-up blocker, leading to the occasional pop-up storm. Now the Safari shortcut adds in an extra shift key, reducing the likelihood that anyone would accidentally toggle the pop-up blocker status. It's not a major change, but it's one that pays off huge dividends in the user experience. Bravo, Apple.

One thing that greatly increased my frequency of accidental presses on this one is that Cmd-K takes you to the Google search field in Firefox. I use Firefox on a PC at work, so I'm pressing Ctrl-K in the browser all day. At home I use Safari, and I always expect that keystroke to take me to the search field.
Why is the Safari application menu in your second screen shot in the form of an icon?
