Jason Snell, Macworld:

You probably already know about Dark Mode and desktop Stacks and Gallery View, but they are just the top-level features in a surprisingly deep update. There are other fun features hiding just beneath the surface.

Here are some of my favorite “hidden” features of the Mojave beta.

Read the post, all good stuff, but this is by far my favorite:

Taking screenshots on the Mac isn’t remotely new, but in Mojave it’s been given a friendly interface, all hiding behind the keyboard shortcut Command-Shift-5.

And:

When you type that shortcut, a floating palette appears that offers you all sorts of options—all of which have been available before, but not in one place. You can grab the entire screen, just a window, or a selection. You can easily change the default folder for saving screenshots, which used to require a trip to the Terminal. You can record video screenshots, which used to require a trip to QuickTime Player. You can take timed screenshots—giving you five or ten seconds to set up the screen exactly as you want it—which was a feature previously available in the venerable Grab utility.

I love this move. The minute you get Mojave installed on your machine (which you’ve carefully backed up), give command-shift-5 a try. Worth it.
