Here are some key mappings that I've become dependent upon:
(global-set-key [(control \,)] 'goto-line)
(global-set-key [(control \.)] 'call-last-kbd-macro)
(global-set-key [(control tab)] 'indent-region)
(global-set-key [(control j)] 'join-line)
(global-set-key [f1] 'man)
(global-set-key [f2] 'igrep-find)
(global-set-key [f3] 'isearch-forward)
(global-set-key [f4] 'next-error)
(global-set-key [f5] 'gdb)
(global-set-key [f6] 'compile)
(global-set-key [f7] 'recompile)
(global-set-key [f8] 'shell)
(global-set-key [f9] 'find-next-matching-tag)
(global-set-key [f11] 'list-buffers)
(global-set-key [f12] 'shell)
Some other miscellaneous stuff, mostly for C++ development:
;; Use C++ mode for .h files (instead of plain-old C mode)
(setq auto-mode-alist (cons '("\\.h$" . c++-mode) auto-mode-alist))
;; Use python-mode for SCons files
(setq auto-mode-alist (cons '("SConstruct" . python-mode) auto-mode-alist))
(setq auto-mode-alist (cons '("SConscript" . python-mode) auto-mode-alist))
;; Parse CppUnit failure reports in compilation-mode
(require 'compile)
(setq compilation-error-regexp-alist
(cons '("\\(!!!FAILURES!!!\nTest Results:\nRun:[^\n]*\n\n\n\\)?\\([0-9]+\\)) test: \\([^(]+\\)(F) line: \\([0-9]+\\) \\([^ \n]+\\)" 5 4)
compilation-error-regexp-alist))
;; Enable cmake-mode from http://www.cmake.org/Wiki/CMake_Emacs_mode_patch_for_comment_formatting
(require 'cmake-mode)
(setq auto-mode-alist
(append '(("CMakeLists\\.txt\\'" . cmake-mode)
("\\.cmake\\'" . cmake-mode))
auto-mode-alist))
;; "M-x reload-buffer" will revert-buffer without requiring confirmation
(defun reload-buffer ()
"revert-buffer without confirmation"
(interactive)
(revert-buffer t t))
