Mac users can use Shift-Command-5 to open the capture controls or Shift-Command-4 to quickly capture a portion of the screen.

Theoretically, you can use the Print Screen to take a picture, but I have another snipping program that uses that key so I couldn't verify it.

I had a hard time figuring out where it was, but watching this 3 minute Microsoft video explained that it was available under the notifications (mine are disabled whenever I'm in full-screen mode, which I almost always am). There's a keyboard shortcut for this Windows Logo + Shift + S.

Windows users may be able to use the Snip & Sketch app.

I tell my students to be sure to remember where they save the file so they can find it later and to change the name (the default is capture.png). Once you drag the window and capture the portion of the screen, go to File > Save As. There's a note that it is moving, but this has been the standard for a while.

Windows users can use the Snipping Tool by going to the search box and typing Snip.

What you cannot do is copy and paste a picture directly into Canvas, although there have been some long-standing feature requests for that capability. In the last half-year, Canvas has changed the process so you can upload directly into the discussion rather than having to upload it first - it made the process much easier. The basic idea is to take a screenshot of a portion of the screen, save it as a portable network graphic (PNG) file, upload it to Canvas, and then embed it in the discussion. To take a screenshot is dependent upon what operating system you are using and what software you have available.
