Are you sure this is available in interactive mode? I tried it, but there is no such Control to cancel it under Windows, because I am also a Mac. I also tried the interactive mode under Mac, and it seems that there is no such Cancel button.
If you are not talking about interactive mode, then the one next to "+" is underscore. In Mac, C means "Command". I think there is something wrong with your quote, because the default BASH key position of the entire Mac or Linux It is consistent with emacs. For example, in BASH, the forward and backward characters are "C+F", "C+B" respectively, and the jump of words are "M+F", "M+B", Cancel It is also consistent with emacs, that is to say, it is "C+_". I have never encountered the saying that in the interactive mode mentioned here, the hotkey to cancel is "C+_".
