这些是readline快捷方式。我经常使用的一些快捷方式：
Ctrl + a => End of line
Ctrl + e => Start of line
Ctrl + l => Clear screen
Ctrl + k => Cut text from cursor position till end of line
Ctrl + u => Cut text from cursor position till start of line
Ctrl + y => Paste text that was cut using above two shortcuts
Ctrl + d => Delete a letter after cursor
Ctrl + h => Delete a letter before cursor
Meta + d => Delete the word after cursor
Meta + f => Move cursor one word forward
Meta + b => Move cursor one word backwards.
