Keyboard shortcut CAPSLOCK-SHIFT-TAB not working in Chrome on external keyboard after CAPSLOCK modified to CONTROL On my Macbook Pro with High Sierra 10.13.3, I have an Apple external keyboard. I used System Preferences &gt; Keyboard &gt; Modifier Keys... to make CAPSLOCK into another CONTROL key:



With this configuration, I can move one Chrome tab to the right with CAPSLOCK-TAB, very convenient.

However, moving one tab to the left with CAPSLOCK-SHIFT-TAB doesn't work on the external keyboard.

It does work on the laptop's built-in keyboard, oddly.

This is not Chrome's fault, because I see the same behavior in the Sublime Text app.
you can use Apple's wireless keyboard, that will solve your problem.
