Touch Bar tip No. 1
If you use a MacBook Pro with the Touch Bar, you can press Shift-Command-6 to grab an image of what is on your Touch Bar. Want to grab an image to place into the document you’re typing in? Just tap Control-Shift-Command-6 and the picture will be saved to your Clipboard for pasting it in.
Touch Bar tip No. 2
This MacBook Pro Touch Bar tip is particularly useful if you find that you often accidentally tap the Siri button: You can change where that button is located so you’re less likely to tap it by accident. Open Keyboard Preferences and choose Customize Control Strip. Look at the Touch Bar, and you’ll see the icons are slightly agitated. Move your cursor to the bottom of your screen and keep moving (as if you’re moving it off the screen); you should see one of the items in your Touch bar highlighted. Now move your cursor to highlight the Siri button and then drag and drop that button a space or two to the left.
(This is also an excellent way to become familiar with how you can edit other items in your Touch Bar.)
Touch Bar tip No. 3
Do you use the function keys regularly in some apps? You can get to them, of course, by pressing the ‘fn’ character. But it’s also possible to set up the Touch Bar so it always shows the function keys in those apps. To do this, open Keyboard System Preferences, select Function Keys, and tap +. You can then select the app(s). Don’t worry if you want to use a regular Control Strip command when you’re using one of the apps — just press Fn to get back to that view.
