Vim备忘

代码折叠

经常使用快捷键 ——不必定准确，仅供参考。

• za 打开/关闭在光标下的折叠
• zA 循环地打开/关闭光标下的折叠
• zc 关闭 (close) 在光标下的折叠
  • 折叠，只折叠最外层的折叠
• zC 循环关闭 (Close) 在光标下的全部折叠
  • 对所在范围内全部嵌套的折叠点进行折叠，包括嵌套的全部折叠.
• zd 删除 (delete) 在光标下的折叠。仅当 ‘foldmethod’ 设为 “manual” 或 “marker” 时有效。
• zD 循环删除 (Delete) 光标下的折叠，即嵌套删除折叠。
  • 仅当 ‘foldmethod’ 设为 “manual” 或 “marker” 时有效。
• zE 除去 (Eliminate) 窗口里“全部”的折叠。
  • 仅当 ‘foldmethod’ 设为 “manual” 或 “marker” 时有效。
• zfap 将光标移到段落内，而后按zfap，就能够自动对整个段落添加折叠标签
• zj 向下移动。到达下一个折叠的开始处。关闭的折叠也被计入。
• zk 向上移动到前一折叠的结束处。关闭的折叠也被
• zm 这将折叠更多 (M-ore)。你能够重复 “zr” 和 “zm” 来打开和关闭若干层嵌套的折叠，否则得一个一个的用zc来折叠.
• zM 关闭全部折叠
• zo 打开 (open) 在光标下的折叠
  • 展开折叠，只展开最外层的折叠.
• zO 循环打开 (Open) 光标下的折叠
  • 对所在范围内全部嵌套的折叠点展开，包括嵌套折叠.
• zr 假定你已经建立了若干折叠，而如今须要阅览所有文本。你能够移到每一个折叠处，并键入”zo”。若要作得更快，能够用这个命令:zr
• zR 打开全部的折叠
• 你能够用 |zn| 命令快速禁止折叠功能。而后 |zN| 恢复原来的折叠。|zi| 切换于二者 之间。
• [z 到当前打开的折叠的开始处。
• ]z 到当前打开的折叠的末尾处。

Alpha helix     (Hh) :   323 is  43.89%
310  helix       (Gg) :     0 is   0.00%

将 Alpha helix (Hh) : 替换成 Alpha helix :

%s/\s\+([^()]\+)\s\+/ /

关键点：括号

2015.5.7

一行变多行，这样子能够：1s/; /\r/g

换行符替换成空格：1,$s/\n/ /
