The double and single arrow buttons in Quick Develop (in the Library module) make the following changes:
• Exposure 1/3 stop, 1 stop
• All others (Contrast, Highlights Shadows etc.) 20 and 5.
• The Temperature and Tint sliders are dependent on the file format. When working with JPEG files, you guessed it, the changes are in increments of 20 and 5. For raw images, the increments for Temperature and tint are also 20 and 5. However in this case they are being calculated in relative percentage terms. (Camera raw translates the relative percentage amount to the absolute temperature and tint value using curve functions – both are quadratic and perhaps not as obvious!)
• Finally, holding the Option + (Mac) | Alt + (Win) in the Library module will change the Clarity and Vibrance settings to Sharpening and Saturation in the Quick Develop panel.
