By the Way
DEFINITION: This idiom is a casual way of adding to a conversation or transitioning a conversation to another topic.

EXAMPLE: "I think that I will go to bed early tonight." "Oh, by the way, have you replaced the batteries in the alarm clock?"
"I finally finished the integration of your comments... I was really impressed how fast you could grasp the idea and use a more elegant way to express it."
