How to copy/select a whole file or buffer in Emacs?

Is there any command to select the whole file contents in Emacs?

For example, Control+a selects whole contents of a file in Notepad, Notepad++, etc.

I can select whole contents using the mouse, but it's inconvenient for large files. I found the basic Emacs commands here and here, but could not find what I am looking for.

How do I select all and copy in Emacs?

Emacs menu > Options > C-x/C-c/C-v Cut and Paste (CUA). That option will let me use Shift + Arrow keys to select, Ctrl + C to copy, and ctrl + V to paste.

How do I copy and paste between Files in Emacs?

An Emacs copy is the command kill-ring-save (usually bound to M-w ). A system copy is what you typically get from pressing C-c (or choosing "Edit->Copy" in a application window). An X copy is "physically" highlighting text with the mouse cursor. An Emacs paste is the command yank (usually bound to C-y ).

How do I select a block of text in Emacs?

You can select blocks of text in Emacs just as you would in most other environments. You could, for example, drag your mouse over a region. You could also hold down the Shift key and use arrow keys. But Emacs also has a number of commands that let you work in larger semantic units.

C-x h will select the entire buffer.

You can search for help within Emacs using the built-in help system.

C-h f will look for help for specific functions. In this case, you could have searched for whole-buffer to find mark-whole-buffer.

Other help commands of interest would be:

  • C-h m to show available commands for the current modes
  • C-h v for help related to variables
  • C-h k to find which functions keys are bound to
  • C-h w to see which key bindings are defined for a given function
  • C-h ? to see which other options are available.

Note that C-x h will only highlight all the text. To actually copy the selected text, you must use C-w for cut (kill-region) or M-w for copy (kill-ring-save).
