Don't mess around with CTL-A

Anybody who uses lots of keystrokes when computing knows that CTL-A (select all) is one of your bestest friends. It's very handy, especially when dealing with large numbers of files. Today at work, unfortunately, the relentless keystrokes backfired when I accidentally mis-clicked something and instructed Adobe Acrobat to open 900 .pdf files at once. Within seconds my desktop was a mess of cascading windows. Even my Mac couldn't survive the onslaught and crashed.
