copied!<p>I have set several shortcuts in my .emacs file. The most useful are:</p> <p>C-tab to switch between the R command line and the file (similar to josh answer, but much faster):</p> <pre><code>(global-set-key [C-tab] 'other-window) </code></pre> <p>Control and up/down arrow keys to search history with matching what you've already typed:</p> <pre><code>(define-key comint-mode-map [C-up] 'comint-previous-matching-input-from-input) (define-key comint-mode-map [C-down] 'comint-next-matching-input-from-input) </code></pre> <p>Comment-uncomment a selected region with C-d or C-maj-d</p> <pre><code>(defun uncomment-region (beg end) "Like `comment-region' invoked with a C-u prefix arg." (interactive "r") (comment-region beg end -1)) (define-key ess-mode-map (kbd "C-d") 'comment-region) (define-key ess-mode-map (kbd "C-S-d") 'uncomment-region) </code></pre> <p>Also I've also enabled CUA mode (from options menu) and reconfigured quite a lot of shortcuts to require only two keystrokes (instead of four in standard mode):</p> <pre><code>;; Delete selection when pressing [delete] key (delete-selection-mode t) ;; ESS Mode (.R file) (define-key ess-mode-map "\C-l" 'ess-eval-line-and-step) (define-key ess-mode-map "\C-p" 'ess-eval-function-or-paragraph-and-step) (define-key ess-mode-map "\C-r" 'ess-eval-region) ;; iESS Mode (R console) (define-key inferior-ess-mode-map "\C-u" 'comint-kill-input) (define-key inferior-ess-mode-map "\C-w" 'backward-kill-word) (define-key inferior-ess-mode-map "\C-a" 'comint-bol) (define-key inferior-ess-mode-map [home] 'comint-bol) ;; Comint Mode (R console as well) (define-key comint-mode-map "\C-e" 'comint-show-maximum-output) (define-key comint-mode-map "\C-r" 'comint-show-output) (define-key comint-mode-map "\C-o" 'comint-kill-output) ;; Search with C-f / C-F (control-maj-F for backware search) (global-set-key "\C-f" 'isearch-forward) (global-set-key (kbd "C-S-f") 'isearch-backward) (define-key isearch-mode-map "\C-f" 'isearch-repeat-forward) (define-key isearch-mode-map (kbd "C-S-f") 'isearch-repeat-backward) ;; Save with C-s / C-S (global-set-key (kbd "C-s") 'save-buffer) (global-set-key (kbd "C-S-s") 'write-file) ;; need to redefine them for isearch mode (don't know why) (define-key isearch-mode-map (kbd "C-s") 'save-buffer) (define-key isearch-mode-map (kbd "C-S-s") 'write-file) ;; Pause = dedicate window.
