## Q&A

  Q What function is used to create a mode-hook when the hook isn't provided by the mode?

  A The setq function.

  Q Can more than one add-hook statement for the same mode be used in the .emacs file?

  A Yes, new hooks can be added at any time.

  Q What effect does byte-compiling a Lisp file have?

  A A byte-compiled Lisp file is more compact and loads faster, but in this form it is no longer readable as a text file.

  Q What is the difference between autoloading a file and loading it with load-library?

  A An autoloaded file isn't actually loaded until it is needed, whereas a file loaded with load-library is loaded into memory from the start.

  Q What happens when a file is loaded with require?

  A The require function only loads a file if it hasn't already been loaded.
