One trick I've learned recently is how to send a YouTube video link at a specific timestamp. It's super useful when I want a colleague to see exactly where something happens in a video without them having to laboriously search through the video for that point.
There are two ways I can do this: One is I can simply right-click on a YouTube URL at the point in the video I want to highlight and select Copy video URL at current time, or else I can manually enter the timestamp at the end of the URL in the format &t=ymxxs where y is the minute value and xx is the seconds.
