Command to change the value of "Use the Caps Lock key to switch to and from U.S."

Question

I'm currently developing my own macOS dotfiles.

I wasn't able to find a command that I can use to change the value of "Use the Caps Lock key to switch to and from U.S." I was trying to find it by using the defaults command.

I need a command to turn it on.

Answer 1

I found one useful trick. In order to find the defaults key for this setting, I opened terminal and wrote next command:

defaults read > 1

Then I turned this setting off and executed:

defaults read > 2

And then after we saved 2 files, we can find the difference:

diff 1 2

Here I was trying to find the key in the defaults which was affected, and I found it.

Here is a command for changing the value of "Use the Caps Lock key to switch to and from U.S.":

# Use the Caps Lock key to switch to and from U.S.
defaults write NSGlobalDomain TISRomanSwitchState -int 1
# Possible values: `0` - off, `1` - on
