One of the little but great enhancements in Lightroom 5 is the ability to see your images in Full Screen with one click – just hit F. I use this feature all of the F’in time now!
Who doesn’t want to see their images in all of their full screen glory?
I used to hit tab (to get rid of the side panels) and then L (for lights out) to get something that isn’t this good. Now, I say “F” it all and just hit F.
Love the little features in Lightroom 5 that make editing images better.
