如何在Emacs中的术语模式下转到命令开头？

Question

I am running bash terminal under Term: line run mode inside Emacs.

Often I want to go to beginning of a command (not beginning of line, which includes the prompt). ie In below line, I 'd like to go to s (not p ).

prompt> some command text here

May I know what is the key shortcut in doing so, if any?

Cc Ca ( term-bol ) is intended to do this. It works by moving to the beginning of the line, and then skipping forward past the prompt, as defined by the buffer-local term-prompt-regexp variable.

However the default value for that regex is just ^ (which therefore has no effect in this situation); so you would need to set it yourself. There are some useful examples in that variable's help text.

Some alternative options are:

• Use term-char-mode instead (in which case Ca works).
  You can switch to char mode with Cc Ck and back to line mode with Cc Cj .

• Copy that same binding for Ca for term-line-mode , so that it does the same thing in both modes:

   (define-key term-mode-map (kbd "Ca") 'term-send-raw) 

• Create a new binding which does the same thing. eg:

   (define-key term-mode-map (kbd "sa") (lambda () (interactive) (term-send-raw-string (string 1)))) 

  nb Using (string 1) because Ca is ascii value 1. See the definition of term-send-raw .
