emacs ibuffer tip: mouse click to open file
(defun xah-ibuffer-keys () "Modify keymaps used by `ibuffer'." (local-set-key (kbd "<down-mouse-1>") 'ibuffer-visit-buffer-other-window) ) (add-hook 'ibuffer-hook 'xah-ibuffer-keys)
Select the above code, then press 【Alt+x eval-region】, or restart emacs.
This will make the mouse click open the file into a split pane. What if you want to open the file without splitting the window? Hint: find out the function name for opening the file in ibuffer. (use “describe-key”.)
