Art has made some notes on a page from a Zoom meeting to help you learn where different functions are and how to use them on a computer. Most of the same functions are available on a tablet, and many even on a phone, but they are in different places. Look around for them.
One secret to doing digital stuff is to be sure you look around the entire screen: top, corners, sides, bottom. Some things appear only when you scroll over them, whether with a mouse or a finger. Don’t be afraid to play around a bit (at least before a meeting starts). Hope this helps.
