Exiting Pkg REPL-mode

[johnnybonney]

I am currently using the online version of Think Julia -- thanks for providing this great resource.

I am brand new to Julia and have been working my way through the book, and I noticed that at the beginning of Chapter 4, it explains "Packages can be installed in the REPL by entering the Pkg REPL-mode using the key ]." However, I was unable to find anything about how to exit Pkg REPL-mode. (Perhaps it is in the book, but I couldn't find it.)

I was stuck in Pkg REPL-mode for an embarrassing amount of time before I found here that it is as simple as pressing Backspace or CTRL+ C on an empty line.

Given that you explain how to enter Pkg REPL-mode, I thought it would be useful to briefly explain how to exit Pkg REPL-mode as well.
