C-M-p
C-M-n
如同 Visual C++ 的括號追蹤，游標可以來回跳至成對的括號位置。
小技巧，遇到 { 時，游標要放在括號的位置上
遇到 } 時，游標要放在括號的右邊一格
C-c C-p
C-c C-n
從游標處往上找，移至最近的 #ifdef
從游標處往下找，移至最近的 #endif 後面一格
C-c C-u
移至上一層的 #ifdef
[ Note ] C-c 是 mode specific command 之意，在此例就是 C mode
C-x C-b
列出 buffers list
C-x C-→
C-x C-←
跳至前後一個 buffer
C-x C-q
toggle buffer read only
M-% string RET new-string RET
Replace string with new-string
C-M-% gregexp RET new-string RET
Replace some matches for regexp with newstring.
C-h a [RET] apropos-key
可以用某些 key word 找出命令。例如讓 apropos-key 為 `window` 就會找出含有 `window` 字串的命令。
C-x {
buffer window 水平變大
C-x }
buffer window 水平變小
C-x z
重複上一個指令動作，緊接著直接按 z 就可再重複
C-h i
可以在 emacs 裡面看 info pages, 進去後，按 [m]emacs [RET] 可以跳進 emacs info 閱讀。（其實就是在emacs里邊閱讀 info pages）
例如：在
(emacs)Top:: > *Note Keyboard Macros:: > Save Keyboard Macro 一節，
可以找到有關設定 macro 的方法。
M-n 餵給命令所需參數
以 C-v （往上捲動，內容往下）這命令為例，內定的參數是捲動一整頁，若給它前面加參數1，像這樣：
M-1 C-v
就只會往上捲一行了。參數也可以是負數喔！例如這樣按：
按住 "Alt" 然後按 "-" "1" 然後放開 "Alt" 就是輸入參數 -1 的意思，mini-buffer 表示為
M- M-1
用在剛剛的命令就成了 ：M- M-1 C-v "往下捲動一行" 了。
OK, 亂玩一下，恰好有個命令是往下捲動一頁 M-v
所以 M- M-1 C-v 效果等於 M-1 M-v，都會往下捲動一行
另外 C-u 是輸入參數 4 的意思
C-u C-v 往上捲 4 行，C-u C-u C-v 表示會捲 16 行喔
C-s C-w ... C-s
尋找 String, 中間的 C-w 可以從游標處往後選字，直到你要尋找的字整個進來為止，接著按 C-s 就可以望下開始找了！超好用！
M-x set-buffer-file-coding-system RET unix
or
C-x <RET> f unix <RET>
把 Dos 文字格式(\r\n)轉為 Unix文字格式(\n)
M-x delete-trailing-whitespace <RET>
移除多餘的行尾空白，符合 Linux Coding Style
