Macworld ’s forums continue to be a veritable cornucopia of Mac 911 fodder. This time, our topic is courtesy of reader bbfaf2, who writes:

After installing iTunes 7, I was entertaining my grandson with visualizer and he hit some keys and the screen went black. Now whenever I turn the visualizer on it shows the song in the lower left hand corner and the Apple logo in the center, but no effects appear. Both the title info and logo fade, as they should after 30 seconds or so. Any ideas on what happened?

As someone with a small child who loves to bang on keys, I feel bbfaf2’s virtual (and visualizer) pain. What likely happened is that our reader’s grandson hit one of the visualizer’s configuration keys. You see, most iTunes visualizers—including the default one as well as most third-party visualizer plug-ins—can be configured by pressing the appropriate keys on the keyboard. Which keys those happen to be depends on the visualizer being used, but most visualizers will show you a list of them by pressing the ? key while the visualizer is active.

Back to the problem at hand, the most important key for bbfaf2 happens to be D , which, when using iTunes’ default visualizer, resets the visualizer’s settings to their defaults—thus bringing back the cool effects our reader has been missing since his grandson had the run of the keyboard.
