LR3: Shortcuts For Comparing Photos
Adobe has done a great job with Lightroom 3 by keeping the same keys as Lightroom 2. Amost all of the shortcut keys, the 235 of them, from Lightroom 2 work in Lightroom 3. If that's not enough for you, John Beadworth wrote a plugin to add your own shortcut keys. Of all of these shortcut keys, I use a couple of dozens, like P R… Please note than some of these shortcuts use positions that the fingers, at least mine, were not built for.
