Use highlight-symbol to toggle highlighting of the symbol at point throughout the current buffer. Use highlight-symbol-mode to keep the symbol at point highlighted.

The functions highlight-symbol-next, highlight-symbol-prev, highlight-symbol-next-in-defun and highlight-symbol-prev-in-defun allow for cycling through the locations of any symbol at point. Use highlight-symbol-nav-mode to enable key bindings M-p and M-p for navigation. When highlight-symbol-on-navigation-p is set, highlighting is triggered regardless of highlight-symbol-idle-delay.

highlight-symbol-query-replace can be used to replace the symbol.
