+This defcustom allows for the customization of the modifier key used

+** JS mode
+
+---
+*** JSX syntax is now automatically detected and enabled.
+If a file imports Facebook's 'React' library, or if the file uses the
+extension '.jsx', then various features supporting XML-like syntax
+will be supported in 'js-mode' and derivative modes.  ('js-jsx-mode'
+no longer needs to be enabled.)
+
+---
+*** New defcustom 'js-jsx-detect-syntax' disables automatic detection.
+This is turned on by default.
+
+---
+*** New defcustom 'js-jsx-syntax' enables JSX syntax unconditionally.
+This is off by default.
+
+---
+*** New variable 'js-jsx-regexps' controls JSX detection.
+
+---
+*** JSX syntax is now highlighted like SGML.
+
+---
+*** JSX code is properly indented in many more scenarios.
+Previously, JSX indentation usually only worked when an element was
+wrapped in parenthesis (e.g. in a 'return' statement or a function
+call).  It would also fail in many intricate cases.  Now, indentation
+should work anywhere without parenthesis; many more intricacies are
+supported; and, indentation conventions align more closely with those
+of the React developer community (see 'js-jsx-align->-with-<'),
+otherwise still adhering to SGML conventions.
+
+---
+*** New defcustom 'js-jsx-align->-with-<' controls '>' indents.
+Commonly in JSX code, a '>' on its own line is indented at the same
+level as its opening '<'.  This is the new default for JSX.  This
+behavior is slightly different than that used by SGML in Emacs, where
+'>' is indented at the same level as attributes, which was also the
+old default for JSX.
+
+This is turned on by default.  To get back the old default indentation
+behavior of aligning '>' with attributes, set 'js-jsx-align->-with-<'
+to nil.
+
+---
+*** Indentation uses 'js-indent-level' instead of 'sgml-basic-offset'.
+Since JSX is a syntax extension of JavaScript, it makes the most sense
+for JSX expressions to be indented the same number of spaces as other
+JS expressions.  This is a breaking change, but it probably aligns
+with how you'd expect this indentation to behave.  If you want JSX to
+be indented like JS, you won't need to change your config.
+
+The old behavior can be emulated by controlling JSX indentation
+independently of JS, by setting 'js-jsx-indent-level'.
+
+---
+*** New defcustom 'js-jsx-indent-level' for different JSX indentation.
+If you wish to indent JSX by a different number of spaces than JS, set
+this variable to the desired number.
+
+---
+*** New defcustom 'js-jsx-attribute-offset' for JSX attribute indents.
+
+---
+*** New variable 'js-syntactic-mode-name' controls mode name display.
+Previously, the mode name was simply 'JavaScript'.  Now, when a syntax
+extension like JSX is enabled, the mode name is 'JavaScript[JSX]'.
+Set this variable to nil to disable the new behavior.
+
+---
+*** New function 'js-use-syntactic-mode-name' for deriving modes.
+Packages deriving from 'js-mode' with 'define-derived-mode' should
+call this function to add enabled syntax extensions to their mode
+name, too.
