如何在 emacs 上按 Ctrl + A？

Question

I'm new to emacs, how can I highlight all text and copy on emacs? enter image description here

Answer 1

• Cx h runs the command mark-whole-buffer (select all)
• Mw runs the command kill-ring-save (copy)

As with many programs, you can find both "Select All" and "Copy" in the Edit menu -- where you can also see the aforementioned key bindings being advertised.

Answer 2

As phils said, you can find it in the Edit menu, with the main keyboard shortcut Cx h .

Furthermore, you can see ALL the key bindings by typing ctrl-h k and then clicking menu Edit > Select All , leading emacs to open an *Help* buffer containing:

<menu-bar> <edit> <mark-whole-buffer> runs the command mark-whole-buffer (found in global-map)

It is bound to s-a, C-x h, <menu-bar> <edit> <mark-whole-buffer>.

If you run emacs on a mac computer, you'll notice the key binding sa which refers to the mac standard shortcut cmd-a (press and hold the cmd modifier and type the letter a ).

Otherwise, on any emacs, you may also type Mx mark-whole-buffer RET (which can be useful if you want to insert in an emacs-lisp function) or the sequence M-< Cx SPACE M-> (which can be useful if you want to skip the first line of the buffer for example).
