Emacs: Mouse Click to Highlight Matching Words

By Xah Lee. Date: . Last updated: .

You can set mouse right-click to call isearch-forward-symbol-at-point (highlight clicked word).

Here's the command.

(defun xah-mouse-click-to-search (Click)
  "Mouse click to start `isearch-forward-symbol-at-point' (emacs 24.4) at clicked point.

Version 2016-07-18"
  (interactive "e")
  (let ((xp1 (posn-point (event-start Click))))
    (goto-char xp1)

Here's the code to set the mouse (this example is for Linux only):

;; set mouse
 ((eq system-type 'windows-nt)
 ((eq system-type 'gnu/linux)
  ; right button
  (global-set-key (kbd "<mouse-3>") 'xah-click-to-search))
 ((eq system-type 'darwin) ; Mac

Note: mouse button and wheel have different syntax on {Microsoft Windows, Mac OS X, Linux}. To find the syntax, Alt+x describe-key, then press the button or wheel. [see Emacs Init: Mouse Config]
