3 cool features of the new macIOS Mojave ver 10.14.2

There are a number of new improvements on the new macOS, but below are my top 3 favourite useful cool features.
- View a File by pressing Space Bar
To take a quick look at a file, image or pdf, point to the file and press space bar. This saves you opening the app. You can make changes using the mark-up tool to crop, rotate an image, add signature to pdf among others.
2. Capture what’s on your screen – still image
As in the previous macOS High Sierra, the screen shot key command combination is the same ie Command + Shift + 4 to take a screen shot on the portion of the screen, or Command + Shift + 3 to capture the whole screen, which will then automatically save the captured image on the desktop or default location on your computer.
In Mojave version, use the same key combination but a thumbnail image will be displayed on the right-hand side of the screen, and if you select the thumbnail, you can access the mark-up features that will enable you to edit, crop, rotate among others.
3. Screen video capture
Rather than opening QuickTime app, this has been simplified. To take a screen video, press Command + Shift + 5 to either record the entire screen or selected portion of the screen.
Command + Shift + 5 again to stop recording. The video capture will be saved on the desktop.
