There are two methods to capture screenshots in TuneFab Screen Recorder for Mac:
1) Take screenshots with hotkeys. Just enter the hotkeys to take screenshots. If you don't know what the default hotkeys are, go to "Gear" button > "General" > "Hotkeys" to check your hotkeys. You can also change the hotkeys to the one you like.
2) Take the screenshots by clicking the "Camera" button. You can click the "Screenshot" icon from the main interface to capture a screenshot.
