Your Canon EOS 77D camera's touch screen works much like the ones found on smartphones and other touch-based devices. When the touch screen is enabled, as it is by default, you can simply touch the monitor to choose menu commands, change picture settings, scroll through your pictures, and more.

How you touch the screen depends on the task at hand. Here's a rundown of the names assigned to various touch-screen moves, or gestures:

  • Tap: Tap a finger on the monitor. (Figures and instructions throughout the book indicate exactly where to tap.)
  • Drag: Using light pressure, drag your finger across the screen. On some menu screens, for example, you can drag up or down to scroll through a list of options.
  • Swipe: Drag one or two fingers quickly across the screen. You use this gesture, known in some circles as a flick, to scroll through your pictures in Playback mode, just as you do when showing off your photos on a smartphone.
  • Pinch in/pinch out: To pinch in, place your thumb at one edge of the screen and your pointer finger at the other. Then drag both toward the center of the screen. To pinch out, start in the center of the screen and swipe both fingers outward. Pinching is how you zoom in and out on pictures during playback.

You can customize two aspects of touch-screen behavior:

  • Adjust (or disable) the touch-screen response: You can choose from three settings, accessed via the Touch Control option, found on Setup Menu 3 and shown here. Standard is the default, setting the screen to respond to a "normal" amount of pressure. Don't ask how the Powers That Be decided what that pressure level is — just know that if your normal pressure doesn't evoke a response, you can change the setting from Standard to Sensitive. Choose Disable to make the touch screen totally inactive.
  • Silence the touch screen: By default, the touch screen emits a tiny "boop" with every tap. If you find that annoying, choose the Beep option, found just beneath the Touch Control option on Setup Menu 3. The option that keeps the boop silent is Touch to Silence — silence indicated by a little speaker with a slash through it. The Disable setting turns off both touch-screen sounds and the beep the camera emits when focus is achieved.
