I would like to ask regular ESS/R users what key bindings do they use frequently and tips on using ESS/R.

C-c C-z ess-switch-to-end-of-ESS
is nice to jump from your source file that you are editing foo.R to the R console

I have set several shortcuts in my .emacs file. The most useful are:
C-tab to switch between the R command line and the file (similar to josh answer, but much faster):
(global-set-key [C-tab] 'other-window)
Control and up/down arrow keys to search history with matching what you've already typed:
(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)
Comment-uncomment a selected region with C-d or C-maj-d
(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)
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):
;; 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)
You will find many more useful shortcuts in ESS documentation.

Can I modify Ctrl r to ess-eval-line-and-step when no code is selected and ess-eval-region when code is selected? This will make it more like Rgui.exe.
