Unclear instruction for quitting monitor

[urbite]

In the Installing and configuring VS Code video, at the 17:45 mark, there is some instruction on how to exit monitor mode and get a terminal prompt again. I was unable to understand what keyboard combination instruction is being given.

It sounds to me like the instructor says "...if I press CTRL + then 'that' key, then that terminations this window.". After playing it back repeatedly I still can't understand what key should pressed in addition to CTRL - 'that' is what it sounds like to me.

After some googling, I found that CTRL+[ is the key combination to exit monitor mode and get the command prompt back.

A minor point, but it added to my confusion was the statement that "...then that terminates this window". But no window is terminated or closed, only the monitor mode is terminated and terminal mode is active again - in the same window.

A suggestion for rewording: "...if I press CTRL + right-square-bracket, this terminates monitor mode and returns control to the terminal command prompt."

Excellent course and videos thus far. Not trying to be picky, just a suggestion that might make this step easier to follow for others.
