On my Macbook Pro with High Sierra 10.13.3, I have an Apple external keyboard. I used System Preferences > Keyboard > 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.
