Here are a few essential cropping shortcuts for Lightroom:
• Access the Crop tool by tapping the R key. Note: even in the Library Module, tapping R will take you to the Develop Module.
• To apply the crop, tap the Return (Mac) /Enter (Win) key.
• Escape removes the crop (or resets the crop to start of editing session of current image).
• Command + Option (Mac) / Control + Alt (Win) + R will reset the crop.
