Use the Touch Bar on Mac
If your Mac has a Touch Bar, you can use familiar gestures—like tap, swipe, or slide—directly on the Touch Bar to adjust settings, use Siri, access function keys, and do tasks in different apps.
The Control Strip, located at the right end of the Touch Bar, lets you ask Siri or easily adjust common settings—just tap the buttons or, for settings like brightness and volume, quickly swipe left or right on the buttons. You can also expand the Control Strip to access more buttons.
Expand the Control Strip: Tap , or press and hold the Fn key on the keyboard (if you set that key to show or expand the Control Strip in Keyboard preferences).
Use Control Strip buttons: Tap the buttons to adjust settings, use Mission Control or Launchpad, or control video or music playback. For some settings—such as display brightness—you can touch and hold the button to change the setting.
Collapse the Control Strip: Tap .
Other buttons in the Touch Bar vary depending on the app you’re using or the task you’re doing. Each app is different—try out the Touch Bar to see what you can do.

Tip: In some apps, you can customize the Touch Bar to add buttons for the tasks you do most often.

In apps where you can change the color of text or objects, you can use the Touch Bar to select a color, shade, or mode (such as RGB or HSB).
Select a color: Touch and hold , then slide your finger to a color.
Select a shade: Tap , touch and hold a color, then slide your finger to a shade.
Select a mode or custom color: Tap , tap the color list on the left, then tap a color mode, such as RGB. To use a custom color you saved, tap Swatches.
Use the sliders for a mode to change values, such as hue or saturation. To save your changes to Swatches, tap the color (a + appears), then tap it again (a checkmark appears).
Hide colors or the color values: Tap in the Touch Bar.
Many macOS keyboard shortcuts use function keys (F1 through F12). For example, you can use F11 to show the desktop.
Press and hold the Fn key on the keyboard to show the function keys in the Touch Bar.
Make sure you customize the Touch Bar in Keyboard preferences so the Fn key shows function keys.
Tap a function key.
If a keyboard shortcut includes a modifier, such as Option or Command, press and hold the Fn key with the modifier key. For example, to use Control-F3 to move to the Dock, press and hold the Fn and Control keys together, then tap F3 in the Touch Bar.
