+When running a command, you can use extra syntax that micro will expand before
+running the command. To use an argument with a space in it, simply put it in
+quotes. You can also use environment variables in the command bar and they
+will be expanded to their value. Finally, you can put an expression in backticks
+and it will be evaluated by the shell beforehand.
