Vim

TO DO:
vim configure:

• show syntax color
• show line number
• convert tab into space
  -tab = 4 spaces

• You can enter insert mode from normal mode by pressing the i key. Now, text you type will be inserted. You can enter visual mode from normal mode by pressing the v key. That starts a visual selection.

-------- moving cursor ----------

• w moves one word forward; 3w moves three words forward; b moves one word backward; 3b moves three words backwards.
• gg moves to first line, G moves to last line, 123G moves to line number 123.
• More moving: 8k moves eight lines up, 5j moves five lines down, 4l moves four characters right, 23h moves 23 characters left.

--------- undo and redo -----------

• Use u to undo and Ctrl-r to redo, multiple times.

---------- copy, paste, delete ---------------

• Use v to enter into visual mode to select lines
• Use d or x to delete / cut
• After selecting: y will "yank" (copy); p will "put" (paste) at a new location (after the cursor; use P for before the cursor). Use y in visual mode and p in normal mode.
• Convenience commands: dd delete current line; yy yank current line.

----------- search ----------

• Searching: /regularexpression to search forward, ?regularexpression search backward; press n for next hit, or N for previous.

======== vim 分屏 ==========
http://coolshell.cn/articles/1679.html

vim分屏功能总结
vim的分屏功能

总结起来，基本都是ctrl+w然后加上某一个按键字母，触发一个功能。
（1）在shell里打开几个文件并且分屏:
　　vim -On file1 file2 ...
　　vim -on file1 file2 ...

大O表示垂直分割(vertical)，小o表示水平分割（默认horizontal），后面的n表示分几个屏，实际上我觉得不用写，默认按后面要分割的文件数来决定分几个屏。
（2）在vim里打开一个分屏:
　　创建空白分屏：
　　:new
　　打开任意文件：
　　:vsplit(:vsp) filename
　　:sp(split) filename
　　打开当前文件：
　　ctrl+w 和 s(split)
　　ctrl+w 和 v(vsplit)

（3）关闭一个分屏:
　　:only 或者 ctrl+w 和 o取消其它分屏，只保留当前分屏
　　ctrl+w 和 c(close)
　　只剩最后一个分屏以后推出：
　　ctrl+w 和 q(quit)
（4）移动光标，也就是切换分屏；也可以移动分屏，比如将左分屏移动到右边。
　　ctrl+w 和 w（各种切换，只有两个分屏的时候还是比较方便的）
　　ctrl+w 和 h(H) 左
　　ctrl+w 和 j(J) 下
　　ctrl+w 和 k(K) 上
　　ctrl+w 和 l(L) 右
（5）最后就是改变分屏尺寸的操作了。
　　ctrl+w 和 < 左
　　ctrl+w 和 > 右
　　ctrl+w 和 + 上
　　ctrl+w 和 - 下
　　ctrl+w 和 = 恢复均等
