Yes, learn the J-K-L key system! It's a huge time saver.
• Awareness nubs are on F and J keys so they're easy to find, find the J key with your finger.
• Your other fingers fall naturally on K and L keys.
• K in the middle is stop, or slow.
• J is to the left, so plays backward to the left in a Timeline.
• L is to the right, so plays forwards on the Timeline.
• Tap either J or L again to play 2x speed, again for 4X speed, again for 8x speed, etc.
• Hold K while using J or L to play in slow motion.
