automatic and manual symbol highlighting for Emacs
Add the following to your .emacs file:
(require 'highlight-symbol)
(global-set-key [(control f3)] 'highlight-symbol)
(global-set-key [f3] 'highlight-symbol-next)
(global-set-key [(shift f3)] 'highlight-symbol-prev)
(global-set-key [(meta f3)] 'highlight-symbol-query-replace)
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 (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.
