Emacs: Paste or Paste Previous

By Xah Lee. Date: . Last updated: .

Here's a command that paste text, and if repeated, paste the previous item.

If a numerical argument is given, paste that many times.

(defun xah-paste-or-paste-previous ()
  "Paste. When called repeatedly, paste previous.
This command calls `yank', and if repeated, call `yank-pop'.

When `universal-argument' is called first with a number arg, paste that many times.

    (when (and delete-selection-mode (region-active-p))
      (delete-region (region-beginning) (region-end)))
    (if current-prefix-arg
          (dotimes (_ (prefix-numeric-value current-prefix-arg))
      (if (eq real-last-command this-command)
          (yank-pop 1)

Emacs paste command is named yankCtrl+y】, and paste previous command is named yank-popAlt+y】.

[see Emacs: Copy/Paste history, kill-ring]

xah-paste-or-paste-previous command combines them, so now you only need one key, instead of 2 keys for 2 commands.

You can set the yank key for it, like this:

(global-set-key (kbd "C-y") 'xah-paste-or-paste-previous)
