在 irb 中导航命令行的键盘快捷键

Question

我看过用户运行 irb 的截屏视频，当他们编写文本时，他们会跳转到行的开头/结尾以及单词的开头/结尾。用于执行此操作的击键是什么？这取决于所使用的外壳吗？

Answer 1

Ctrl + A => Move to beginning of line
Ctrl + E => Move to end of line 

这些是 readline 命令

这是一个 cheatsheet 您一般而言可能会有所帮助

Answer 2

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.
