Signature
(highlight-symbol-at-point)
Documentation
Highlight each instance of the symbol at point.
Uses the next face from hi-lock-face-defaults without prompting,
unless you use a prefix argument.
Uses find-tag-default-as-symbol-regexp to retrieve the symbol at point.
If REGEXP contains upper case characters (excluding those preceded by \)
and search-upper-case is non-nil, the matching is case-sensitive.
This uses Font lock mode if it is enabled; otherwise it uses overlays,
in which case the highlighting will not update as you type. The Font
Lock mode is considered "enabled" in a buffer if its major-mode
causes font-lock-specified-p to return non-nil, which means
the major mode specifies support for Font Lock.
Probably introduced at or before Emacs version 24.4.
