org: Emphasis and monospace

 
 Emphasis and monospace
 ----------------------
 
 You can make words *bold*, /italic/, _underlined_, ‘=verbatim=’ and
 ‘~code~’, and, if you must, ‘+strike-through+’.  Text in the code and
 verbatim string is not processed for Org mode specific syntax, it is
 exported verbatim.
 
    To turn off fontification for marked up text, you can set
 ‘org-fontify-emphasized-text’ to ‘nil’.  To narrow down the list of
 available markup syntax, you can customize ‘org-emphasis-alist’.  To
 fine tune what characters are allowed before and after the markup
 characters, you can tweak ‘org-emphasis-regexp-components’.  Beware that
 changing one of the above variables will no take effect until you reload
 Org, for which you may need to restart Emacs.
