I am stuck and cannot escape. It says:
type :quit<Enter> to quit VIM
But when I type that it simply appears in the object body.
Hit the Esc key to enter "Normal mode". Then you can type : to enter "Command-line mode". A colon (:) will appear at the bottom of the screen and you can type in one of the following commands. To execute a command, press the Enter key.
:q to quit (short for :quit):q! to quit without saving (short for :quit!):wq to write and quit:wq! to write and quit, attempting to force the write if the file lacks write permission:x to write and quit; like :wq but writes only if modified (short for :exit):qa to quit all (short for :quitall):cq to quit, without saving, with a nonzero exit code to indicate failure (short for :cquit)You can also quit Vim directly from "Normal mode" by typing ZZ to save and quit (same as :x) or ZQ to just quit (same as :q!). (Note that case is important here. ZZ and zz do not mean the same thing.)
Vim has extensive help - that you can access with the :help command - where you can find answers to all your questions and a tutorial for beginners.
