ESS/R的有用键盘快捷键和提示

Question

我想向常规的ESS/R用户询问他们经常使用的关键绑定以及使用ESS/R的提示.

Answer 1

我在.emacs文件中设置了几个快捷方式.最有用的是:

C-tab在R命令行和文件之间切换(类似于josh的答案,但更快):

(global-set-key [C-tab] 'other-window)

控制和上/下箭头键可搜索历史记录,并匹配您已输入的内容:

(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)

注释 - 使用Cd或C-maj-d取消注释所选区域

(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)

此外,我还启用了CUA模式(从选项菜单)并重新配置了很多快捷键,只需要两次击键(而不是标准模式下的四次):

;; 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. 
  (defun toggle-current-window-dedication ()
   (interactive)
   (let* ((window    (selected-window))
          (dedicated (window-dedicated-p window)))
     (set-window-dedicated-p window (not dedicated))
     (message "Window %sdedicated to %s"
              (if dedicated "no longer " "")
              (buffer-name))))
  (global-set-key [pause] 'toggle-current-window-dedication)

;; delete = delete
  (global-set-key [delete] 'delete-char)

;; C-b = list buffers
  (global-set-key (kbd "C-b") 'bs-show)

您将在ESS文档中找到更多有用的快捷方式.
