In iPhoto 08 (iPhoto 7) you can preview the photos contained in an Event by slowly moving the mose pointer left-right while hovering, somewhat similar to the coverflow in iTunes. But if you have many photos in an Event, it may be a bit tricky moving your mouse pointer pixel by pixel.

So what do you do? You select the Event thumbnail and then preview the contents with the left and right arrows on your keyboard.

While previewing photos this way, you may want to change the key photo as well. There are two ways of doing this, one is to right-click and select ‘Make key photo”, or simply press spacebar and the current photo will be set as a key photo.

I’ve just noticed a strange change when in edit mode. When editing a photo, you can always preview the original and compare it to the edited one before saving.

In iPhoto 06 you do this by pressing Control key. In iPhoto 08, for some reason you have to press Shift key. I wonder why.
