Oooh. Neat. Lightroom Trick

Hey! Rebel Fish was working in LR and happened to press the option key while in Library mode. If you have the quick-Develop pane open with Tone Control, etc. extended, you will see Clarity change to Sharpen and Vibrance change to Saturation. Your keywords (if shown) will display how many images are in that particular keyword. If you’re in Develop mode, you’ll see the settings give you an option to reset.
Try it. It’s super fun.
