Also, `focus-read-only-mode` is provided, which is a mode optimized for continuous reading. It inhibits change in the buffer, hides the cursor and provides bindings for moving between *things* (defined in [Thing At Point](http://emacswiki.org/emacs/ThingAtPoint)). One can toggle `focus-read-only-mode` with <kbd> M-x focus-read-only-mode </kbd> or <kbd> C-c C-q </kbd> if `focus-mode` is enabled.
The amount of dimness can be customized by setting the `focus-dimness` variable, where a positive integer indicates a more dim color (i.e. more blended with the background color of your theme), and a negative integer indicates a less dim color.
Focus uses the [Thing At Point](http://emacswiki.org/emacs/ThingAtPoint) library to choose what section should be in focus. By default, modes derived from `prog-mode` uses `defun`, and modes derived from `text-mode` uses `sentence`. This a customizable by setting the `focus-mode-to-thing` variable, which is a list containing pairs on the form `(mode . thing)`.
