Emacs: Add Web Browser Back Key/Button to Info mode
Web browsers on Windows use the ⌫ Backspace for moving to last viewed page.
Here's how to make ⌫ Backspace key to emacs's info mode 〔►see Emacs: View Info Page〕. Put the following in your emacs init file.
(defun add-browser-backspace-key-to-Info-mode () "Add some browser styled nav keys for `Info-mode'. The following keys are added: 【Backspace】 for `Info-history-back' 【Shift+Backspace】 for `Info-history-forward'." (progn (local-set-key (kbd "<backspace>") 'Info-history-back) (local-set-key (kbd "<S-backspace>") 'Info-history-forward) ;; (local-set-key (kbd "<mouse-8>") 'Info-history-back) 5-button mouse. the mouse numbering depends on your OS and mouse. Call “describe-key” then press mouse button to find out ) ;; note: on Linux Firefox, you have to turn on Backspace key for previous page. In the preference. http://xahlee.info/mswin/Firefox_set_backspace_previous_page.html ) (add-hook 'Info-mode-hook 'add-browser-backspace-key-to-Info-mode)
5 Buttons Mouse, Setting Forward/Backward Thumb Buttons for Info
if you have 5-buttons mouse, you can also make the 4th button do “previous page”.
describe-key 【Ctrl+h k】, then press the mouse button. Emacs might say:
<mouse-8> … undefined
② add the following in your info key function given above.
(defun add-mouse-back-button-to-Info-mode () "Add some browser styled nav keys for `Info-mode'." (local-set-key (kbd "<mouse-8>") 'Info-history-back)) (add-hook 'Info-mode-hook 'add-mouse-back-button-to-Info-mode)
I recommend you get a 5-buttons mouse, because the extra buttons lets you do lots of things. You do use mouse a lot, because 50% of time you spend in browser even for coding, and in browser the mouse is most efficient.
