Ubuntu:文本编辑器nano快捷键一览
nano是比vi更简单易用的文本编辑器，在nano界面只列出了几个常用的快捷键，而实际上nano支持的快捷键远不止这些。
下面是nano的说明：
The nano editor is designed to emulate the functionality and ease-of-use of the UW Pico text editor. There are four main sections of the editor. The top line shows the program version, the current file name being edited, and whether or not the file has been modified. Next is the main editor window showing the file being edited. The status line is the third line from the bottom and shows important messages. The bottom two lines show the most commonly used shortcuts in the editor.
即：编辑器顶行显示程序版本、当前被编辑的文件名、以及文件是否已经编辑过；接着是主编辑框，显示正在编辑的文件；倒数第三行为状态行，用来显示重要的信息；底部的两行则显示编辑器中最常用到的快捷键。
The notation for shortcuts is as follows: Control-key sequences are notated with a caret (^) symbol and can be entered either by using the Control (Ctrl) key or pressing the Escape (Esc) key twice. Escape-key sequences are notated with the Meta (M-) symbol and can be entered using either the Esc, Alt, or Meta key depending on your keyboard setup. Also, pressing Esc twice and then typing a three-digit decimal number from 000 to 255 will enter the character with the corresponding value. The following keystrokes are available in the main editor window.
即：下面的快捷键符号中，^为Control键（Ctrl)，或连按两次Escape键（Esc）;M为Meta键（Windows下为Alt键）；另外，连续按下两次Esc键后再输入000-255之间的三位数字，则会输入该ASCII码对应的字符。
示例：^G即按下Ctrl键然后按G；M-/即按下Alt键然后按/键。
